Son Seals is really one of the titans of the current blues scene who should be spoken of in the same conversation as BB King, Buddy Guy, and Ronnie Earl.  Of the many albums I have, this is one of the best, Son with his own band burning it up in a club full of real blues lovers.  Although the set here features several covers (Son is one of the great composers, as you'll learn on subsequent albums), they are delivered in quite personal, intense renditions (esp. Litle Walter's "Last Night") that show that Son picked up the best from watching the legends who used to play his father's Arkansas club in the 1950's.  This is one of the  gems on the Alligator label, so by all means buy it along with the others he has in the catalog. His vocals have grit, and his guitar is like a nasty fusion of BB, Albert (King), and Hubert Sumlin.  And see Son when he plays near you.
