One result was the inclusion of two all-instrumental extended jams at the instigation of Bloomfield following the group's successful appearance at The Fillmore in San Francisco during March alongside Jefferson Airplane. Both reflected his love of jazz, as the blue note-laden "Work Song" featuring harmonica by Butterfield had become a hard bop standard, and the title track "East-West" used elements of modal jazz as introduced by Miles Davis on his ground-breaking "Kind of Blue" album. Bloomfield had become enamored of work by John Coltrane in that area, especially his incorporation of ideas from Indian raga music. The album also included Michael Nesmith's song "Mary, Mary," which Nesmith would soon record with his band The Monkees - although original pressings of "East-West" did not include a songwriter's credit for this track.
