Not sure Bill, but I believe this is all about search values. In other words, it's so when people search for, say, David Torn and they find you, they say YEA... I WANNA BUY IT. I don't think it's really so much what you really think you SOUND like, but who you think people might search for that are looking for music like yours. Or maybe your level of 'difference'. Does that make sense?
I think that takes some of the onus off the issue. You sound like Bill Walker - plain and simple. But when people hunt for another artist and CD Baby pops up your name, you would hope that those folks would find your music interesting and wanna buy it. Frisell might be good... even John Fahey might be good. People that look for John's music are looking for different music. The problem with Frissel might be that jazz folks might come sniffing. Jeff Beck might be good.
And I think you can always change these references down the road.
Not having heard what your record sounds like it's hard to say.
It's sort of like 'genre' but more specific. It's for people looking for a new thrill sort of like the old thrill but different.
It's also CD Baby's way of snagging you new friends.
All that matters is that people who get directed to you like what they find, not that you sound like that person. If they wanted that person they'd buy that person.
Just a thought
