Frequently classified as the first album by the group Mountain, which was named after it, Leslie West's initial solo album featured bass/keyboard player Felix Pappalardi, who also produced it and co-wrote eight of its 11 songs, and drummer N.D. Smart II. (This trio did, indeed, tour under the name Mountain shortly after the album's release, even performing at Woodstock, though Smart was replaced by Corky Laing and Steve Knight was added as keyboard player for the formal recording debut of the group, Mountain Climbing!, released in February 1970.) Pappalardi had been Cream's producer, and that power trio, as well as the Jimi Hendrix Experience, were the models for this rock set, which was dominated by West's throaty roar of a voice and inventive blues-rock guitar playing. Though West had led the Vagrants for years and cut a handful of singles with them, this was his first album release, and it made for an auspicious debut, instantly establishing him as a guitar hero and setting the style of Mountain's subsequent recordings.
