Fifty tracks, two acts and a 25-piece band: how Undertale's soundtrack became a world tour
UNDERTALE Symphony is the concert franchise built on Toby Fox's 2015 score, now touring as UNDERTALE: The Determination Symphony — a 25-piece orchestral show that opened in San Jose on 23 August 2026 and is booked through to March 2027.
A score written alone, in FL Studio
The music being played by orchestras in Kuala Lumpur, Boston and Manila this year was written by one person on consumer software. Toby Fox composed all 101 tracks of the Undertale soundtrack in FL Studio, drawing on SNES-era role-playing games and the Touhou Project series, and Materia Collective released the two-disc album on 15 September 2015 — the same month the game itself arrived. It runs two hours and ten minutes.
The album charted in a way soundtracks rarely do for a game made by a tiny team: number five on Billboard's US Soundtrack Albums chart, 21 on US Independent Albums, 25 on the UK Soundtrack Albums chart. iam8bit pressed a vinyl edition in 2016. Critics singled out Fox's use of leitmotif — character themes that reappear, recombined, across the score, with "Hopes and Dreams" folding earlier material back in at the climax.
One piece outgrew the rest entirely. "MEGALOVANIA", written for the Sans boss fight, became one of the most widely circulated pieces of game music of the last decade; a version of it was performed at a papal audience in January 2022. It is the reason a 25-piece orchestra can sell out a 2,000-seat theatre in Pittsburgh, and it is the piece every arrangement of this material has to land.
Ten years of concerts before the world tour
The live history starts in Japan. MUSIC Engine gave the first orchestral performances of the score at Suntory Hall in Tokyo on 6 May 2019 and at The Symphony Hall in Osaka on 15 July 2019. A remastered recording of the Tokyo matinee was distributed online by Fangamer and 8-4 in September 2020 as the 5th Anniversary Concert — for several years the only way most people outside Japan heard this music played by an ensemble.
A different model was tried in Chicago on 11 January 2020, when AWR Music Productions staged Undertale Live at the Studebaker Theater with the Fifth House Ensemble, using audience voting to decide which way the performance went — the concert equivalent of the game's branching routes.
Japan then built out a touring circuit: the Undertale Symphonic Concert Tour, released through Nippon Columbia and directed by Masaki Yamamoto, played nine Japanese cities between March and May 2025, and MUSIC Engine's Undertale 10th Anniversary Concert ran from September 2025 into May 2026. The decisive date for the current show, though, was 22 June 2025, when Lambert Jackson Productions put a 10th-anniversary orchestral concert into the Eventim Apollo in London and had to add a matinee. That London run is the direct ancestor of the tour now circling the world.
The Determination Symphony, announced March 2026
The tour was announced on 17 March 2026, with tickets going on general sale that week — the Las Vegas date, for instance, opened on AXS on 19 March 2026. The billing is specific about what it is and is not: a 25-piece orchestra playing new arrangements, with synchronised gameplay footage on a screen above the players, tracking the game's geography from the Ruins and Snowdin through Waterfall and Hotland to New Home.
The arrangements are by the British orchestrator Adam Hoskins. Fox is credited as curator rather than arranger, and his contribution to the press material was characteristically flat: Undertale is a game with a lot of music, he said, and it is good when skilled professionals play it and people listen to it. Production sits with Lambert Jackson Productions in partnership with Materia Music, with the 2026–27 world tour produced by the Tokyo live-music company SOHO Live.
It opened at the San Jose Center for the Performing Arts on 23 August 2026 and is scheduled across more than 70 shows in two legs covering North America, South America, Europe, Asia and Australia. The legs overlap: 5 November 2026 carries both a Pittsburgh date at the Benedum Center and a Melbourne date, because the orchestras are contracted regionally rather than flown as a single band. In Asia the playing has been done by Singapore's Metropolitan Festival Orchestra and, in Manila, by Filharmonika, both under the conductor Thanapol Setabrahmana.
Where the tour stands in November 2026
As of early November 2026 the tour is roughly halfway through. The North American autumn run has already taken in Kansas City on 2 September, Boston's Wang Theatre on 19 September, Portland on 5 October, Detroit on 8 October, Resorts World Theatre in Las Vegas on 10 October and Vancouver's Queen Elizabeth Theatre on 18 October; the Asia leg played KLCC Plenary Hall in Kuala Lumpur on 28 September and the Makati Proscenium in Manila on 17 October.
The schedule immediately ahead is dense. November 2026 brings Orlando's Walt Disney Theater and the New Jersey Performing Arts Center on the 7th, both with matinee and evening performances, Berlin on the 11th, a second British run through Liverpool on the 12th, Halifax on the 13th, Grimsby on the 14th and Newcastle on the 15th, Mesa Arts Center on the 14th, Montreal on the 19th and 20th, Ottawa on the 21st, Sydney on the 27th, and Brisbane on 3 December.
The 2027 dates extend well past that: Edmonton on 9 January, the Hawaii Theatre in Honolulu on 16 January, Barcelona on 15–16 February, Madrid on 17–18 February, Dublin on 21 February with two shows, Glasgow on 28 February, then São Paulo on 2–3 March, Santiago on 6 March, Buenos Aires on 9–10 March and Lima on 12–13 March. Ticket pricing is theatre-standard — Boston's started at $49.50 — and some rooms sell VIP packages; the Las Vegas booking advertised dedicated entry, banquettes with cocktail service and two VIP lounges. Cosplay is encouraged at the door, but face-concealing masks and costume weapons are not allowed in.
What the show is actually like, and what reviewers have said
The programme is longer than most game-music concerts attempt: over 50 pieces in two acts, with Act One running 29 tracks from "Once Upon a Time" to "ASGORE" and Act Two running 22 from "Nyeh Heh Heh!" to "MEGALOVANIA". In Kuala Lumpur on 28 September that came to 120 minutes including a short interval. The ensemble is not a straight orchestra: strings, woodwind, brass and percussion are joined by electric guitar, bass, drums and keyboards, which is how the heavier battle material keeps its edge. Game sound effects are cued into the mix, and the footage is cut to the music rather than the other way round, with the player character's name set to "You".
The staging has a streak of in-jokes for people who know the score. The conductor's handling of "Dogsong" departs from normal practice, some players are given blank pages, and the apparent ending is followed by "MEGALOVANIA" as an encore — in Kuala Lumpur it was played again in brief after the conductor's closing remarks, to the loudest cheer of the night. Reviewers in Malaysia and the Philippines reported standing ovations, audible sing-alongs on "Oh! One True Love", applause for individual character entrances, and lobbies that stayed full of cosplayers after the house lights came up. The only technical complaint from the KLCC show was the mix on "Your Best Nightmare", which was pushed too loud for the hall.
The sharpest criticism so far came from Kotaku, writing on 3 September about the Kansas City performance the night before. The reviewer rated the playing and the arrangements, and the audience, but counted eleven tracks missing from a show otherwise built on completeness — including the ordinary random-encounter battle theme, Hotland's central motif and Undyne's battle music, an omission the piece called out directly. That is the recurring tension of this tour: the programme is large enough to feel like the whole score, which makes every gap conspicuous.
The show, now
The current show runs about two hours in two acts with a short interval, and there is no support act — the orchestra is the whole bill. Over 50 pieces are played in game order, Act One covering 29 tracks from "Once Upon a Time" to "ASGORE" and Act Two covering 22 from "Nyeh Heh Heh!" to "MEGALOVANIA", so the evening tracks the Ruins, Snowdin, Waterfall, Hotland and New Home in sequence. Twenty-five players — strings, woodwind, brass and percussion plus electric guitar, bass, drums and keyboards — perform under a large screen carrying gameplay footage cut to the music, with game sound effects folded into the mix and the player character named "You". Conductors speak to the room between numbers; the Asia leg was led by Thanapol Setabrahmana with locally contracted orchestras. Expect audible sing-alongs on "Oh! One True Love", applause when particular characters appear on screen, and "MEGALOVANIA" held back past the credits sequence as the encore, which drew the biggest reaction of the night in Kuala Lumpur on 28 September 2026 and a standing ovation. Reviews of the Malaysian and Manila shows were strongly positive, with one noting the mix on "Your Best Nightmare" was too loud for the hall; Kotaku's 3 September review of the Kansas City date praised the playing but counted eleven tracks absent, including the standard battle theme, Hotland's main motif and Undyne's battle music. Halls range from 1,000-seat theatres to casino rooms with VIP banquettes; cosplay is welcomed, but face-concealing masks and costume weapons are refused at the door.
