The version of Yes heard on this collection of their earliest BBC recording differs greatly from the cosmic prog-rockers who defined their genre throughout the '70s. On their first two albums, which provide most of the material for these live-in-studio performances, Yes pursued a relatively raw, visceral, post-psychedelic sound. Heavily inspired by Vanilla Fudge's reinventions of contemporary pop tunes, Yes peppered their early repertoire with radically reimagined versions of songs from The Beatles ("Every Little Thing"), Buffalo Springfield ("Everydays"), and even West Side Story ("Something's Coming"), all expanded into wild art-rock rave-ups. Guitarist Peter Banks and keyboardist Tony Kaye sported a tougher, simpler sound than their more famous replacements (Steve Howe and Rick Wakeman). And even on gently melodic tunes like love ballad "Sweetness," the band have a distinct psych-pop sound. Plus, these performances pack even more energy and excitement than their studio counterparts.
