Blues songs...
The 1st time I really sat down to listen to 'em was when I picked up a 2nd-hand CD of Muddy Waters...and the 1st song that really hit me was, "Dont Go No Farther"...It still is one of my all-time faves. to this day...
Another song called, "Bad, bad Whiskey"... I believe by Junior Wells and Willie Dixon...Only heard it a few times..but that was enough to get me hooked...
For getting down, nothing beats, "Sweet Home, Chicago" by Robert Johnson
