Issued hard on the heels of the revolutionary chaos of 1968 — the Chicago Democratic Convention riots, the street battles in Paris, the Reverend Martin Luther King Jr. and Robert F. Kennedy's assassinations — Miles Davis's album Bitches Brew stood the music world on its ear. Often referred to as the seminal jazz-rock recording, the album attracted more rock fans and open-minded hippies than it did jazz aficionados, who were offended by the numerous elements Davis introduced that defied longstanding jazz traditions and structures. Two of the key cogs in Davis's new sound were guitarist John McLaughlin and pianist Chick Corea. McLaughlin proved himself to be one of the great extemporaneous guitarists of his age with amazing, powerful runs that cut across the complex fabric of the music. Corea was already a respected jazz pianist, but can be said to have made his bones with his astounding solo work on "Miles Runs The Voodoo Down," a track that stands out even on such a remarkable album. Corea has gone on to record notable projects with many of the greats in modern jazz — check out 1973's Light As A Feather, with Brazilian vocalist Flora Purim — while McLaughlin has become an international icon for his work with the Eastern-­oriented Mahavishnu Orchestra. What voodoo these two jazz geniuses will run down when they take the Verizon stage in a five-piece ensemble is anybody's guess, but no one who loves the spontaneous combustion of great jazz should miss this once-in-a-lifetime show that just may rock a little too.
