Problem: Background: Electric Ladyland is the third and final studio album by English-American rock band the Jimi Hendrix Experience, released in October 1968 by Track Records/Polydor, and Reprise Records in North America. The double album was the only record from the band produced by Jimi Hendrix. By mid-November, it had charted at number one in the United States, where it spent two weeks at the top spot. Electric Ladyland was the Experience's most commercially successful release and their only number one album.
Context: Recording sessions for the Jimi Hendrix Experience's third and final studio album, Electric Ladyland, began at the newly opened Record Plant Studios, with Chas Chandler as producer and engineers Eddie Kramer and Gary Kellgren. As recording progressed, Chandler became increasingly frustrated with Hendrix's perfectionism and his demands for repeated takes. Hendrix allowed numerous friends and guests to join them in the studio, which contributed to a chaotic and crowded environment in the control room and led Chandler to sever his professional relationship with Hendrix. Redding later recalled: "There were tons of people in the studio; you couldn't move. It was a party, not a session." Redding, who had formed his own band in mid-1968, Fat Mattress, found it increasingly difficult to fulfill his commitments with the Experience, so Hendrix played many of the bass parts on Electric Ladyland. The album's cover stated that it was "produced and directed by Jimi Hendrix". The double LP was the only Experience album to be mixed entirely in stereo.  During the Electric Ladyland recording sessions, Hendrix began experimenting with other combinations of musicians, including Jefferson Airplane's Jack Casady and Traffic's Steve Winwood, who played bass and organ respectively on the fifteen-minute slow-blues jam, "Voodoo Chile". During the album's production, Hendrix appeared at an impromptu jam with B.B. King, Al Kooper, and Elvin Bishop. Electric Ladyland was released in October 1968, and by mid-November it had reached number one in the US, spending two weeks at the top spot. The double LP was the Experience's most commercially successful release and their only number one album. It peaked at number six in the UK, spending 12 weeks on the chart.  Hendrix's studio perfectionism was legendary - he and Mitch Mitchell recorded well over 50 takes of "Gypsy Eyes" over three sessions. Hendrix was generally insecure about his voice and often recorded his vocals hidden behind studio screens. Hendrix sang all the backing vocals himself on the title track and on "Long Hot Summer Night". He was said to be very happy with the vocal results on "Have You Ever Been (To Electric Ladyland)".
Question: How did the rest of the band feel about that
Answer: Redding later recalled: "There were tons of people in the studio; you couldn't move. It was a party, not a session."
