The band Chase was created in 1970 by Bill Chase, Ted Piercefield, Alan Ware, and Jerry Van Blair, all veteran jazz trumpeters who were also adept at vocals and arranging. They were backed up by a rhythm section consisting of Phil Porter on keyboards, Angel South (b. Lucian Gondron) on guitar, Dennis Johnson on bass, and Jay Burrid (b. Jay Mitthauer) on percussion. Rounding out the group was Terry Richards, who was featured as lead vocalist on the first album. In April 1971, the band released their debut album, Chase, which contains Chase's best-known song, "Get It On", released as a single that spent 13 weeks on the charts beginning in May 1971. The song features what Jim Szantor of Downbeat magazine called "the hallmark of the Chase brass—complex cascading lines; a literal waterfall of trumpet timbre and technique". The band received a Best New Artist Grammy nomination, but was edged out by rising star Carly Simon.

Chase released their second album, Ennea, in March 1972; the album's title is the Greek word for nine, a reference to the nine band members. The original lineup changed midway through the recording sessions, with Gary Smith taking over on drums and G. G. Shinn replacing Terry Richards on lead vocals. Although the first Chase album sold nearly 400,000 copies, Ennea was not as well received by the public. One likely reason was a shift away from trumpet sections. As Bill Chase put it in a Downbeat interview, "I don't want people to be heavily conscious of a trumpet section. They should just hear good things, but not be clobbered over the head with brass." A single, "So Many People", received some radio play, but the side-two-filling "Ennea" suite, with its tightly chorded jazz arrangements and lyrics based on Greek mythology, was less radio-friendly.
