Climbing!, also known as Mountain Climbing!, is the official debut studio album by American blues rock band Mountain. Released on March 7, 1970, the album featured the 'classic' Mountain lineup of Leslie West (guitar, vocals), Felix Pappalardi (bass, piano) and Corky Laing (drums, percussion), and followed the West solo album Mountain featuring Pappalardi and drummer Norman Smart, released in 1969 and often credited to the band. Produced by Pappalardi, the album reached number 17 on the American Billboard 200 albums chart and featured the band's best-known song "Mississippi Queen". "For Yasgur's Farm" was actually performed at the Woodstock Festival in August 1969 with another title. It was retitled for the album.
Track timings listed on original 1970 Windfall Records LP pressings of the album differ slightly from the above, with the notable exception that the listed duration of 4:50 for "Never in My Life" is significantly in error.
