Dark Magus is a live recording of a very specific 1974 Carnegie Hall date that included most, but not all, of the members who recorded the classics Agharta and Pangaea. While drummer Al Foster, bassist Michael Henderson, percussionist James Mtume, and guitarists Pete Cosey and Reggie Lucas were all present, the key element of Sonny Fortune was not yet in the band. Saxophonists David Liebman and Azar Lawrence were doubling in the saxophone chairs, while Dominique Gaumont, with his Jimi Hendrix-styled effects and riffs, was the band's third guitarist. The deep voodoo funk that gelled on the aforementioned recordings hadn't yet come together on this night at Carnegie, near the end of a tour.
