Concrete Sox were an early hardcore punk/thrashcore band of the 80's hailing from Birmingham, UK. Fans of the band often consider Concrete Sox an early style crossover band which later was popularized by other bands like Suicidal Tendencies. They mixed hardcore punk influences with huge metal influences in the vein of thrash metal (this is very evident on the bands earlier material, with a very huge Metallica worship sound on some songs.) Concrete Sox were a very outspoken band, lyrically speaking about protecting the environment and animal rights. The band is best known for sharing the stage with bands like Heresy, Doom, Napalm Death, Antisect and other early hardcore punk/grindcore bands.
