The Mahavishnu Orchestra, in its original incarnation, lasted just four years, but in that brief time, the pioneering quintet set both the template and the high-water mark for fusion music. No band ever rocked as hard in a jazzy place as guitarist John McLaughlin’s charging ensemble. McLaughlin had already built a firm reputation in his native England as a keen improviser with blues and rock leanings when he was invited by drummer Tony Williams in early 1969 to join him in New York. Almost immediately, McLaughlin was swept up into the very epicenter of the burgeoning fusion movement, appearing on – in 1969 alone – three of the genre’s most significant recordings: Emergency! (by the newly-formed Tony Williams Lifetime) and In a Silent Way and Bitches Brew, the epochal Miles Davis albums that kick started fusion.
