I've thought about this often... regarding players and songwriters and singers. In my musical career my identity seems to lack a particular signature style... When I write a song it may come out as blues, or it may come out as more of a modern "solo acoustic pop" style of thing. Or something else. I'm just totally eclectic. Popular musicians/singers often seem to have a sound that's easy to identify. Like Rod Stewart's vocals for instance, Janis Joplin, Joe Cocker, SRV's guitar playing. CSN&Y's harmonies, Joni Mitchell etc. You can ID them in the first few seconds of a song. It seems to a large extent the reason for their popularity, more important than musicianship or vocal range. (not intended to mean I'm saying they aren't good) What about you? Do you have an identifiable style or are you eclectic?
