The album almost did not sell, since Hendrix lost the master tape of side one of the LP in the back of a taxi in London. Hendrix, Chas Chandler and an engineer called Eddie Kramer had to re-mix the songs in one night. They could not get the song "If 6 was 9" right, but Hendrix's bassist Noel Redding had a copy of it on tape. When the album was released, Hendrix was disappointed that the album was finished so quickly and he thought it could have been done better.
