Slipknot's first album, Slipknot, is a very good album to listen to, Iowa is good as well, and Vol. 3 is my personal favorite of their discography, All Hope Is Gone, which has Psychosocial on it, is a decent album, and .5: The Gray Chapter is decent enough to listen to.I haven't listened to a full album of slipknot, but I really like the song ''Psychosocial''.
