Kiss blew glam rock out of the water when they formed in 1972, their larger than life cartoon personas and pyrotechnic on stage antics drove audiences crazy. By 1978 they were one of the biggest bands in the world, but the relentless schedule of touring and recording combined with the non-stop debauchery of a rock and roll lifestyle would divide the band; while Peter Criss and Ace Frehely descended into a world of drink and drugs, the bandleader's Paul Stanley and Gene Simmons stayed sober and tried to keep Kiss recording and performing. Eventually tensions became too much and the original line up of the band split in 1980 when Peter Criss was sacked. Gene and Peter kept Kiss alive over the next decade, with session musicians hired to fill in for the absent Peter and Ace, but their popularity gradually waned. Then, in 1995, after a brief performance on MTV to a rapturous audience, the original line up reconciled and reformed. But when Kiss immediately began a relentless schedule of tours, old tensions soon resurfaced. By 2000 the band hung together by a thread, and the original line up of Kiss broke up when Peter Criss left for the last time. So what caused the original members of Kiss to finally split?
