He was introduced to punk rock and hardcore music by his Aberdeen classmate Buzz Osborne, lead singer and guitarist of the Melvins, who taught Cobain about punk by loaning him records and old copies of the Detroit-based magazine "Creem". Punk rock proved to be a profound influence on a teenaged Cobain's attitude and artistic style. His first punk rock album was "Sandinista!" by The Clash, but he became a bigger fan of fellow 1970s British punk band the Sex Pistols, describing them as "one million times more important than the Clash" in his journals. He quickly discovered contemporary American hardcore bands like Black Flag, Bad Brains, Millions of Dead Cops and Flipper. The Melvins themselves were a major early musical influence on Cobain; his admiration for them led him to drove their van on tour and help them to carry their equipment. He and Novoselic watched hundreds of Melvins rehearsals and "learned almost everything from them", as stated by Cobain. The Melvins' heavy, grungey sound was mimicked by Nirvana on many songs from "Bleach"; in an early interview given by Nirvana, Cobain stated that their biggest fear was to be perceived as a "Melvins rip-off". After their commercial success, the members of Nirvana would constantly talk about the Melvins' importance to them in the press.
