Where Have I Known You Before is a studio album by American jazz group Return to Forever, the first featuring guitarist Al Di Meola, and the second since leader Chick Corea switched to mostly electric instrumentation, playing music heavily influenced by progressive rock, funk and classical.

[citation needed] Although Return to Forever's style remained unchanged since its previous album, Hymn of the Seventh Galaxy (1973), important changes took place in the band's sound and line-up.

An equally important change was the replacement of guitarist Bill Connors with 19-year-old Al Di Meola.

[6][7] Between the album's longer tracks are three of Corea's short piano improvisations that all bore a title beginning with "Where Have I...".

[9] The track has a long keyboard introduction, after which Chick Corea is joined by the full band, and an "Eastern" theme appears.
