Van Morrison is that rare vocalist who reinvents his songs each time he approaches them. This spectacular double live album, recorded at three venues with the 11-piece Caledonia Soul Orchestra in 1973, features classic blues (“Help Me”) and soul (“I Believe to My Soul”) alongside powerful, intricate versions of Van classics, like “Saint Dominic’s Preview,” “Into the Mystic,” and “Cyprus Avenue.” No overdubs were allowed. As a result, it’s the purest snapshot of a big band working in the rock ’n’ roll era.
