It says on the Sound on Sound article published July 2020 "Another important element in the punchy drum sound that Parker achieves is the fact that he'll often feed a stereo mix of them onto one of his three reel-to-reel tape machines — a Revox B77, Ampex ATR-700 and TEAC A2340R — for added saturation.

"I'd say probably half of the drums on the album were run onto either the Revox or the ATR. I bounced some drums, put them on the tape, took them off and then never went back to the stems. Even if it didn't sound right, or something could've been better, I didn't go revisit from before the tape. It was like, 'These are the drums now... deal with it.'"
