w/Buddy Guy,sound is well mixed w/ both guitars up in the mix. This is an encore from a B.Guy show, just two Blues legends shredding it up w/ ease on a 25 min. "Champagne & Reefer" also has "Mary had a little lamb" (8 min) and an 18 min. "Leave My Girl Alone" 4 tracks in all. Worth it? yes, just for the guitar playing alone. Recommended
