Rock music is a style of music derived from the blues, characterised by a prominent drum beat in 4:4 time, accompanied by electric bass guitar providing the harmonic underpinning for the melody of electric guitar and vocals.
Elvis Presley and Buddy Holly were early pioneers of Rock in the late 1950s, as were the Beatles and Rolling Stones throughout the 1960s. In the 1970s progressive rock started to decline in popularity, and a new style called Punk rock became popular. In the 80s, New wave showed up and became popular. 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 rock subgenre 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.
Rock music sometimes includes lyrics that promote drug use, sex, and violence, but the same is true for other forms of music as well.[1] [2] Some say that anti-Christian sentiment is the driving force behind Rock music. [3]
