Last week's show featured tracks from the newly-released Jimi Hendrix album, Valleys of Neptune, and just a few days before that show I started looking around to see if there were any interesting cover versions of classic Hendrix songs.  I expected to find a few versions of "Purple Haze" (I found over 40) and maybe a few others, since I knew of at least one Hendrix-tribute album, and of course Stevie Ray Vaughan threw down the gauntlet with a Hendrix cover on almost every album.  But I found hundreds: jazz, orchestral, funk, bluegrass - even an all-sitar tribute album(!) - from all over the world.
