Despite being brothers, Oasis members Noel and Liam Gallagher couldn't stand each other! In the '90s when the band was reaching international superstardom, Liam and Noel were constantly fighting on stage, including throwing instruments at each other and changing each other's lyrics.
The two were always quitting and re-entering the band, dropping out of shows last minute, and getting into physical altercations in the studio. In 2009, the band broke up for good, and despite them never continuing to tour or create more music, it seems the feud isn't over. The two still heckle each other over Twitter.
The Smashing Pumpkins are a '90s classic, creating some of the most memorable grunge performances of their time. However, it wasn't always sunshine and lollipops once they exited the stage.
It all started in 1996 when drummer Jimmy Chamberlin shot heroin with their keyboardist Jonathan Melvoin in New York City, which resulted in a nasty overdose that left Melvoin deceased. After the tragedy, Chamberlin continued to use drugs and alcohol and repeatedly missed studio sessions.
A few years later, Chamberlin returned to record a new album, and frontman Billy Corgan apparently began to get way too controlling for bassist D'arcy Wretzky.
The Smashing Pumpkins continued to tour well into the 2000s, but Wretzky never returned, and Corgan says the real reason they're broken up was never due to Chamberlin's addictions, but rather Wretzky's "mean-spirit" and "minimal contributions" to the band.
