Over the years, Bruce Cockburn concerts have evolved from solo performances in moccasins into full-band gigs in army boots. In the beginning, Cockburn travelled around in an old camper truck, a vagabond poet with acoustic guitar in hand and faithful dog, Aroo, at his feet. During the ’80s, he and his group toured in a large streamlined bus, dressed like urban guerrillas wielding an arsenal of electric instruments. By the end of that decade—and for much of the next—Cockburn downsized and performed with just a pair of talented sidemen. But as his superb live recordings reveal, regardless of the era or the size of his entourage, Cockburn’s concerts are always a wonder to behold: expansive, entrancing and full of surprises.
