Many of mine have been covered already by several folks (you guys have good taste

).
There's only one group and one single artist that I have every album they put out (and most DVD concerts) and that's Pink Floyd and SRV. I do have everything by the original Lynyrd Skynyrd but only some of the later albums from the 2.0 version.
If you like blues styled music, particularly SRV, his former bandmates (Double Trouble) made a couple of albums after his death with other lead guitarists and singers. One was Arc Angels featuring an old friend of Stevie's doing vocals and guitar.
Also in the same vein of music, check out Ian Moore, Storyville and Los Lonely Boys.
I don't listen to new "country"..... anything newer than Alan Jackson and George Straight don't cut it except for a few acts. I do like Jamey Johnson.
