Undertale: The Determination Symphony

I do not have sufficient reliable knowledge about an organization specifically named 'Undertale: The Determination Symphony.' It is possible that this could be a concert event or a symphony celebrating or inspired by the music from the popular indie video game 'Undertale,' created by Toby Fox. The game's soundtrack is well-regarded and has been performed by various orchestras worldwide in concert events celebrating video game music. However, specific details about an organization or ensemble solely dedicated to a symphony by this name are not within my current knowledge base.
