 Production started at the Record Plant Studios in New York City, but the band became dissatisfied with the sound there and moved to Los Angeles' Ocean Way Studios.Getting the right drum sound at the Record Plant had proved impossible, with Rubin even isolating the drums in a tent in the studio and lining the walls and ceiling with material to soak up the extra sound the room generated.Although the band was immediately satisfied with the Ocean Way Studios, Rubin and Malcolm Young clashed over the album's direction, with Rubin demanding as many as 50 retakes on some songs, and rumours persist that Rubin was often absent from the studio and left the band to their own devices while he reportedly saw to the recording of the Red Hot Chili Peppers' "One Hot Minute" album at the same time.
