Undertale fans will flock to Twitch this Saturday (November 21) for a special musical event.

Undertale LIVE will be delivered by Fifth House Ensemble, who will unveil new arrangements of beloved Undertale tracks. During the concert, fans can decide to slay or spare foes. Fifth House Ensemble's artistic director Dan Visconti said this about the forthcoming event:

“Undertale LIVE is certainly the only album in which you’ll hear a French horn player imitating the sound of a ghost singing to itself. Using classical instruments to reimagine this videogame fantasy world has led to some incredible creativity. With so many exciting Undertale arrangements and covers in the aether, we wanted above all to contribute something distinctive - and to create a live touring event where fans could experience this music as part of the game’s story, participating in the narrative by voting to slay or spare via text message and driving to a different ending each night.”

The concert will be streaming on Undertale LIVE’s Twitch channel starting at 8:30 EST/5:30 p.m. PST. The concert will be available to purchase digitally during the event. Physical CDs, which will arrive early next year, can be pre-ordered during this time.
