Life (later covered by The Offspring and Zebrahead) and (I Hate) Surfin' in H.B., plus Purgatory II, Stand Up, Eringzo, Falling Out, Hang Ten in East Berlin, Wounds From Within, and Spiritual Law. Lineup features Casey Royer on vocals alongside Adolescents guitarist Rikk Agnew and his brother Alfie Agnew, with John Knight on drums. The songs O.C. Life and Falling Out were originally written by Rikk Agnew for his 1982 solo album All By Myself. Produced by Thom Wilson.
