While Chamberlin performed all drum parts on the album, he would disappear for days on drug benders that caused everyone to fear for his life. After one incident where the drummer had disappeared for two or three days, Corgan "put the hammer down", according to Vig, and had Chamberlin perform the drum part for "Cherub Rock" until his hands bled.

also i love this anecdote

Triclops studio was used because of 2 main reasons, it was not LA and they had a beautiful sounding Neve 8068. I believe Butch sought the studio for the board and wanted to keep the band away from distractions like there would be in LA.
Exactly, that's why we chose the studio...that Neve was a kickass sounding, and we thought we would be isolated enough to keep the distractions low.

However, within 24 hours Jimmy new every drug dealer, hooker, bookie, and nut case in Atlanta...so that part of the plan didn't work!
