Acoustic Rock
Acoustic rock, in the simplest terms, is rock music played on unamplified instruments, typically featuring acoustic guitar, drums, and vocals.
Its appeal lies in that it comes across as more down to earth with its natural, simple and personal sound.
Acoustic rock is different from most acoustic music because it is usually more uptempo and the delivery is more powerful, as opposed to the slow, gentle, subtley emotional delivery of a country ballad.
Most people, upon hearing this term, commonly associate it with the singer-songwriter genre of the 1960s and 70s, as well as certain forms of folk music and pop.
Performers of acoustic music often increase the volume of their output using electronic amplifiers. However, these amplification devices remain separate from the amplified instrument and reproduce its natural sound accurately.
Following the increasing popularity of the television show MTV Unplugged during the 1990s, acoustic, though in most cases still electrically-amplified, performances by musical artists who usually rely on electronic instruments became colloquially referred to as “unplugged” performances.
