Psycho are one of the original crossover bands. They formed in 1982 in Boston. Sadly they have been majorly overlooked due to bands such as Suicidal Tendencies, Cryptic Slaughter and other big hitters. For me, Psycho do it better than most. It sounds like GG Allin is singing for Slayer.
Unfortunately this is only 4 short songs (one of them being a GG cover, coincidentally) but they are all pretty special.
