Months later, at the Isle of Wight Festival, Hendrix gave the tapes to his drummer Mitch Mitchell to have him listen and comment on the necessary rhythm section requirements for recording the songs. After Hendrix's death in September 1970, Mitchell simply forgot about the tapes, apparently unaware that they were one-of-a-kind masters. For 22 years, the "Black Gold" tapes sat in a black Ampex tape box that Hendrix tied shut with a headband and labelled "BG".
