This 1964 concert recording isn’t just one of the best live blues albums—it’s one of the most captivating live records ever made in any genre. B.B.’s a force of nature here, with each vocal moan and growl and every six-string sting bearing the full weight of his power and passion. Backed by gut-punching horns and a startlingly swinging rhythm section, he throws his entire being into tunes like “How Blue Can You Get?” and “Sweet Little Angel”, which have justifiably become blues standards.
