Mark you're killing me limiting me to 3 but I will do my best.
1) SRV Tightrope (the best version is on his Austin City Limits DVD).
2) Ozzy Crazy Train ( which I can play all of except one little chromatic run I know what Randy is doing but I can't make my fingers do it)
3) Pantera Shattered
Being limited to 3 is hard, I didn't get to list anything from Clapton, BB King, John Lee Hooker, Elmore James, ZZ Top, Red Volkaert, (figure out who he is) Bill Kerchen, ect
