Thrash metal took the world by storm in the late eighties and early nineties, but if there was a Spanish scene, it wasn't well known outside of Spain. Muro was probably one of the more well-known Spanish thrash bands of the era, releasing several albums in their homeland during the peak thrash years. Apparently they broke up in the early nineties after releasing Pacto De Sangre in 1992, but reunited several years later, releasing Peligro Imminente in 1999, along with a couple of other releases before breaking up for good.
