First off, everyone that "sounds like SRV" to me personally sounds like a rip-off. Anyone who really loves SRV, and who was brought to the altar of the blues guitar by him (as I was in my early teen years) will have to realize that the master is gone and he will never be replaced.
Kenny Wayne Shepard is good, but he needs to grow up a bit and develop his own style.
Try the new Ronnie Earl- i feel like goin' on-- he's dealing with his manic depression, and this sounds better to me than his last 4 albums--
Glad to see a plug for "little" Charlie Baty of Little Charlie and the Nightcats-- Captured live has some amazing work on it. Highly, highly recommended- there's also a "deluxe Edition" best of Lil' Charlie out there that I never leave home without. Baty is, IMHO, in the top 5 living blues guitarists.
Overall I'm amazed how many of my own favorites were already plugged by you guys-- good suggestions all.
Tab Benoit is great, too- especially his recent album with Jimmy Thackery, and Benoit's last solo album Wetlands. If any of y'all find a copy of "strike a deep chord: Blues guitars for the homeless" BUY IT. Benoit does a smokin' version of "nice and warm" and it's followed by a great instrumental piece that was recorded in a big echo-y room with a killer tube guitar amp -- a real hoot on a system that stages. The whole (compilation) album is great-
My other recommendations that may not necessarily sound like SRV, but are great for blues fans in general that like him in my experience:
Kid Ramos, Son Seals, BB King (of course), Junior Watson, Kenny Burrel, Otis Rush
Keep the suggestions coming, guys
