Melvins, 'King Buzzo' (1992)
In one of his earliest cameos, Grohl contributed production, guitars, drums and vocals to King Buzzo, the Kiss-inspired EP from Melvins' frontman Buzz Osborne. Osborne had introduced Grohl to Nirvana two years earlier, leading the drummer (whose band Scream was in the process of disbanding) to audition for Kurt Cobain's group. "I remember saying to [Scream guitarist] Franz [Stahl] that I was going up to try out for the band," Grohl recalled in 2009. "And he just shook his head and said, 'You ain't coming back.' And deep down I knew it too."
