Pissing Razors was a heavy metal band who originally formed in the late 80's. The band originally was named Back Door Cyclops but decided to change its name and style of music to incorporate more raw sounding vocals. They are musically comparable to local heroes Pantera, Skinlab and Machine Head in other words, angst-filled, shouted vocals are merged with meaty guitar riffs for a sound that's custom-made for the mosh pit. Evolution is the bands sixth full-length album from 2003. The title suggests the change of the music as on this album Pissing Razors were experimenting with a few new styles.
