 It was the band's first album to feature guitarist Pete Friesen, who replaced founding guitarist Tantrum.Friesen contributed to the songwriting and was a major part of the new sound presented on this album, introducing a heavier, riff-based grunge sound compared to the punk leanings of earlier efforts.The subject of the cover art is taken from the artwork ""Jet Age Man" by Ralph Morse, which featured on the cover of "Life" magazine in December 1954.
