A talented trumpeter with a vivid musical imagination and the willingness to try new things, Don Ellis led some of the most colorful big bands of the 1965-75 period. After graduating from Boston University, Ellis played in the big bands of Ray McKinley, Charlie Barnet, and Maynard Ferguson (he was featured with the latter on "Three More Foxes"), recorded with Charles Mingus, and played with George Russell's sextet (at the same time as Eric Dolphy). Ellis led four quartet and trio sessions during 1960-1962 for Candid, New Jazz, and Pacific Jazz, mixing together bop, free jazz, and his interest in modern classical music. However it was in 1965 when he put together his first orchestra that he really started to make an impression in jazz. Ellis's big bands were distinguished by their unusual instrumentation (which in its early days had up to three bassists and three drummers including Ellis himself), the leader's desire to investigate unusual time changes (including 7/8, 9/8, and even 15/16), its occasionally wacky humor (highlighted by an excess of false endings), and an openness towards using rock rhythms and (in later years) electronics. Ellis invented the four-valve trumpet and utilized a ring modulator and all types of wild electronic devices by the late '60s. By 1971, his band consisted of an eight-piece brass section (including French horn and tuba), a four-piece woodwind section, a string quartet, and a two-drum rhythm section. A later unrecorded edition even added a vocal quartet.
