Before there was Bitches Brew, there was Emergency! No group played a more aggressively intimidating electric jazz for its time than drums colossus Tony Williams’s Lifetime, whose 1969 debut reinvented the organ trio as high-volume, high-risk response to rockers like Hendrix and the Who. Cream bassist Jack Bruce, who joined the Lifetime for its explosive 1970 release Turn It Over, pulls the alarm on Williams’s proto-fusion with Spectrum Road, introduced in 2008. Vernon Reid (guitar), John Medeski (keyboards), Cindy Blackman Santana (drums), and Bruce are all familiar travelers in music without borders. There’s no backtracking on their recent debut, either; they hit the road where Williams exited, making this less a tribute than a great notion come of age.
