Rock the Overview!

Rock music can be described as wild, unpredictable and loud music which is unlike its pop music counterpart. A disruptive nuisance to some, but authentic, undiluted pure music to others; rock music is as controversial as its musicians.

Tracing back its history to as early as 1940s, rock music is said to derive from rock 'n roll; the popular, good old music which evolved from a melting pot of jazz, blues and country music. Hard-edged, no-nonsense music usually performed by a band of guitarist, drummer, bassist, and accompanied with the lyrics sung by a vocalist, rock music has diversify and develop into various styles that there is no solid description that can define rock music completely.

With the creation of electrical guitars, rock music broke away from other genres of music in the conservative age as rock musicians sung their songs of sexual freedom. With big names like Chuck Berry and Rolling Stones, rock music dominated the music scene and resume branching into new genres such as heavy metal (darker, heavier tone), progressive rock fueled by psychedelic elements as well as punk music characterized by angst-filled lyrics, loud guitars and rude attitudes.

Today, rock bands are usually indie bands (bands signed to independent labels) or mainstream rock bands, which are less noisier than their indie counterparts. Rock music, in whichever form, would inevitably continue to hover as a major presence in the music industry, with its loyal fans being lower-profiles than pop music fans.
