In terms of both songwriting and sound, "Mono Heart" is everything one might expect from Rave The Reqviem and more – boasting major label production quality while packing both a powerful punch and crystal clear mix. As a taste of things to come from the second album itself, "Mono Heart" is almost certain to leave the listener craving for more. The second bonus track comes in the shape of symphonic ballad "The Antedilvvian Lvllaby" and it presents a very different sound from the intensity usually associated with Rave The Reqviem.
