Eric Clapton

Eleven cameras were used to shoot this concert at the Hartford, Conn. Civic Center, and the finished product still doesn’t show anything higher tech than an oblique angle or two. No matter. It’s an hour of terrific music, with the stern-faced Clapton in fine bluesy form, vocally and on guitar. While the extended versions of Blues Power and Cocaine are especially charged, there’s a simmering vitality throughout. (Vestron, $29.95)
