I'm planning on becoming the lead vocalist/bassist for a band so there's a few that I look up to for inspiration.

Geddy Lee (Rush)
Phil Lynott (Thin Lizzy) (we have the same birthday)
Tom Araya (Slayer)
Andrew Wood (Malfunkshun)
Les Claypool
Greg Lake (King Crimson)
Lemmy
Paul McCartney
Mr. Rust (Rusty Eye)
