The London based instrumental progressive metal project, Miroist, is currently streaming a bonus track that was included with the T-Shirt/EP bundle that Miroist offered. For those who did not purchase it can stream the track in all it’s awesomeness below. The track is called “Build your cities on the slopes of Vesuvius!” and it absolutely rips. Completely jarring grooves and rhythmically complex electric guitar monstrosities occupy the duration of this track. You can stream that bad boy below as well as the debut EP, The Pledge, below.
