The Music Machine was an American rock band formed in Los Angeles, California in 1966. Fronted by chief songwriter and lead vocalist Sean Bonniwell, the band cultivated a characteristically dark and rebellious image reflected in an untamed musical approach. Sometimes it made use of distorted guitar lines and hallucinogenic organ parts, punctuated by Bonniwell's distinctively throaty vocals. Although they managed to attain national chart success only briefly with two singles, the Music Machine is today considered by many critics to be one of the groundbreaking acts of the 1960s. Their style is now recognized as a pioneering force in proto-punk; yet within a relatively short period of time, they began to employ more complex lyrical and instrumental arrangements that went beyond the typical garage band format.
In 1965, the band came together as a folk rock trio known as the Raggamuffins, before expanding to the quintet that was later rechristened the Music Machine. The group was known for their style of dress, clothing themselves in all-black attire.
