After delaying progress on the song for over two years, Hendrix returned to work on "Angel" with Mitchell and bassist Billy Cox in July 1970, during sessions for his planned fourth studio album; the master recording was produced at Electric Lady Studios on July 23, the last of seven takes, and the overdubbing and mixing were completed on August 20 and 21 amongst various other tracks which were ultimately released posthumously. As with the majority of material recorded during this period, "Angel" was produced by Hendrix and engineered by Eddie Kramer.
