The series of Stevie Ray Vaughan concert albums that began with Live Alive (1986) and continued after the guitarist's 1990 death is far from the catalog-bloating cash-in you'd expect from the record company of a platinum seller cut down at a career peak. Instead, each disc gives a distinctly different view of the Texas blues-rocker's stage strengths. Where Live Alive captured Vaughan and his band Double Trouble in full arena roar and In the Beginning recorded a looser early club gig, Live at Carnegie Hall finds the outfit broadening its range with guest shots from Dr. John and the Roomful of Blues horn section. Rather than overpowering Vaughan's signature tautness, the bigger band makes for an entertaining switch--in effect allowing a fresh look at his R&B; roots.
