On August 10th, 1988, The Smashing Pumpkins played a show consisting of Billy Corgan on guitar and vocals, James Iha on guitar, and newcomer D’arcy on bass at the Avalon backed by a drum machine (perhaps this guy). Just one month earlier, Billy and James played a show at a Polish disco named Chicago 21 where Billy was on bass and vocals, James played guitar, and a drum machine backed them up.
The set consisted of ten songs, of which a majority (at least currently known) would never be played again live – such as Arm to the Teeth and Holiday.
