Conception is a compilation album issued by Prestige Records in 1956 as PRLP 7013, featuring Miles Davis on a number of tracks. The album, compiled from earlier 10 inch LPs, or as 78rpm singles, also features musicians such as Lee Konitz, Sonny Rollins, Stan Getz, Gerry Mulligan, and Zoot Sims. The cover was designed by Bob Parent.[2][3] In particular, the entirety of the 10"LP Lee Konitz: The New Sounds (PRLP 116) makes up all of side 1.
"I May Be Wrong" and "So What" were originally issued on the 10"LP Chubby Jackson All Star Big Band (PRLP 105), although they are here credited to Gerry Mulligan.
All six Lee Konitz tracks were originally issued on the 10"LP Lee Konitz: The New Sounds (PRLP 116), which is reissued in its entirety here. The tracks with Miles Davis as a sideman were recorded after Davis' first Prestige session, and before Davis' own debut album, also called The New Sounds (PRLP 124).[4] Konitz and Davis had previously worked together on the Birth of the Cool sessions.
Both Miles Davis tracks were previously released on Miles Davis: the New Sounds (PRLP 124), Davis' first album. The other two tracks from that album were reissued on Dig (PRLP 7012), and "Conception" and "My Old Flame" have been added as bonus tracks to the later reissues of the Dig CD.
