Reviewing for The Village Voice in 1969, Robert Christgau called Spirit "a talented group with guts of cellophane" and lead vocalist/guitarist Randy California "the rock equivalent of the cool, progressive jazzman of the '50s". He commended the album for focusing the better songs on side one of the LP, saying its "mostly excellent rock" shows Spirit "can be very good", but found songs like "Ice" on side two indicative of how "incredibly empty" the band can be as well.
