[[Elvis Presley]] was an early pioneer of Rock, as were the [[Beatles]].

[[Elvis Presley]] and [[Buddy Holly]] were early pioneers of Rock in the late 1950's, as were the [[Beatles]] and [[Rolling Stones]] throughout the 1960s.  In the 1970s the stadium rock of bands such as [[Boston]] and [[Pink Floyd]] became formulaic and overwrought, setting the stage for a backlash called [[Punk rock]] which evolved, with the addition of synthesizers, into [[New wave]] well into the 1980s.  By the latter half of that decade, [[Glam rock]] had stultified into MTV-friendly "hair metal", and the stage was set for Nirvana and the Seattle scene, a darker and heavier version of punk known as [[Grunge]].  By 1994 and the death of Kurt Cobain, grunge had changed into the stable formula of alternative rock that continues to be popular today.
