Mountain was an American hard rock band that formed on Long Island, New York, in 1969. Originally comprising vocalist and guitarist Leslie West, bassist and vocalist Felix Pappalardi, keyboardist Steve Knight and drummer N. D. Smart (soon replaced by Corky Laing), the band broke up in 1972 and has reunited frequently since 1973. Best known for their cowbell-tinged song “Mississippi Queen”, as well as the heavily sampled song “Long Red” and their performance at the Woodstock Festival in 1969, Mountain is one of many bands to be commonly credited as having influenced the development of heavy metal music in the 1970s. The group’s musical style primarily consisted of hard rock, blues rock and heavy metal.
