I grew up a bit earlier: As a keyplayer: late 60ties bluesplayers, no one in particular.
After that Mike Ratlidge (soft machine) and of course (B3!)Keith Emerson (ELP)and Jon Lord.
Keith Jarret was a guy I listened to carerfully.....
In the 80ties I think every keyplayer into programming was aware of David Frank....
Composers/songwriters that really influenced me: above all Joni Mitchell (also as a gtr player, open tunings ....) Nick Drake...
Carole King, Andrew Gold, Kevin Ayers, and of course TODD RUNDGREN....
