In the movie Interstella 5555 by Daft Punk it is insinuated that all genius musicians on Earth are actually aliens kidnapped by an evil manager and turned into humans. Some of them are shown being transformed. The first one is shown as a kid playing piano in a baroque setting, so I am seeing a clear indication that this is supposed to be Wolfgang Amadeus Mozart. On whom are the rest based?
#1 This one I got the reference as Mozart.
#2 This one is later shown with a trumpet.
#3 This one is later shown with a grand piano.
#4 This one is later shown with a classical or an acoustic guitar
