If you're only going to buy one Buddy Guy-album, I'd probably go with Rhino's career-spanning "The Very Best Of Buddy Guy".
But this one is pretty much a must-have as well, so buy two, okay? Rhino's disc does include a handful of Guy's Chess sides, but his years at Chess were arguably his best period, and this excellent 15-track compilation brings together the cream of the crop.
These classic 60s recordings burn with unbridled passion - just listen to the smouldering slow blues "Leave My Girl Alone" and "I Cry And Sing The Blues". George "Buddy" Guy is one of the very few bluesmen whose vocals (occationally) match the intensity of the great Elmore James, and his guitar playing is superb - an obvious source of inspiration to men like Eric Clapton and Stevie Ray Vaughan.
Also, the sound on this anniversary compilation is magnificent. Excellent transfers and spacious stereo mixes make these forty-year old recordings sound as sharp as some or other tired cliché about sharp things coming off the laser beam.
If you are into 60s electric blues, this is a must-have purchase. Highly, highly recommended!
