Sam Greenfield + Toast Club - Band on the Wall 

Sam Greenfield's "Fusioncore" is pitched in G♭ major

"Triumph over evil, obstacles, hurdles. Surmounting foes and finally finding rest in victory. Brilliant clarity of thought and feeling."

Despite the complex key signature, this key sees a lot of action in jazz, particularly in modern compositions. It is one of the happiest keys, with it frequently being used in "feel-good" music in a fast, funk style. Sam Greenfield is a frequent user of this key.
