American crossover thrash metal band Suicidal Tendencies was formed in 1980 by vocalist Mike Muir. To follow up on the success of their self-titled debut album, they released Join The Army in
1987. The album is arguably one of their most popular efforts and features the popular tracks “War Inside My Head”, “Possessed To Skate” and “Join The Army”. It was the first album to feature Rocky George on guitar and R.J. Herrera on drums, and the last recording with Louiche Mayorga on bass.

Join The Army features the track “Human Guinea Pig”, which previously only appeared on CD. The vinyl package also includes an insert with lyrics.
