Jazz/blues guitarist suggestions for SRV fan.

I second the melvin taylor choice > dirty pool
Also try these :
gary moore > still got the blues
robin ford > & the blue line
robert cray > (quite a few good cd's)
tinsley ellis > trouble time , fanning the flame
little charlie & the nightcats > captured live
johnny lang > lie to me

The clone of SRV is Kenny Wayne Shepared. If you want a jazzy instrumental jazz/blues sound like in Riviera Paradise, Ronnie Earl and the Broadcasters, he is the man. He is more jazz/blues like Rivera than versus the other SRV more blues/rock sound (for lack of a better definition) which is one of my all time favorite songs too. Rivera uses more cording on the guitar to create the song where Ronnie's playing is more playing along with the song and some cord based melody. The other guitarists you mention and that others have mentioned do not sound like Rivera at all. I can burn you a copy of a few CDs if you want, just email me.

Happy Listening.

JIMMY THACKERY
LITTLE JIMMY KING
ROY BUCHANAN
MELVIN TAYLOR
KENNY BROWN

Have to second the Jimmy Thackery nomination. Very underrated and overlooked player, IMO. He has a new all-instrumental CD out. Highlight is supposed to be his version of Rude Mood.

Check out Stevie and brother Jimmie's roots with records from
WC Clark the original author of "Cold Shot" an Austin and South Texas blues musician.
Hop Wilson may be another.
There are also some fine Alligator albums with Stevie Ray from the mid 80's A.C. Reed in particular.
