Azrael Rocks is the name of a band that performed during a Smurfstock Festival in the fanfiction story "Smurphony Of The Night". It is a rock band that features Sloppy as its main guitarist and lead vocalist. It is ironically named after the cat Azrael, who was the inspiration for the creation of Sloppy's guitar. The song they perform is called "Smurf This Way", an analog to the popular Aerosmith song "Walk This Way".
The band's logo is the face of Azrael smiling with his teeth bared.
