Disney's annual D23 Expo is happening now, and as part of the festivities, Harmonix unveiled new details about Fantasia: Music Evolved.

Harmonix revealed that all of the classical music for Fantasia: Music Evolved was recorded at Abbey Road Studios with the London Symphony Orchestra. Harmonix's community developer Eric Pope sent out a number of Vines and tweets showcasing Fantasia's stage presence, which included orchestrations of Vivaldi's Four Seasons (Winter), and Night On Bald Mountain gameplay.
