Pray For Teeth - Demo
The production on a whole keeps things pretty dark, as the higher end brightness is pretty absent. Though, it seems to work, not sounding muddy or overly bass heavy. The high gain guitars rage over top of some very pummeling drums, as the vocals stay in the lower register of the things, belting out a sustained growl.
The band mixes up tempos and drum work which keeps the listener on their toes (check out "Hive" for a good example of how seamlessly this band can change things up). You get some classic d-beat here, but you also get a nice variety of mid tempo, slow and even some sludgy moments. "Puritan Eyes" seems to be the Opus, coming in at 7:27 sitting mainly in a slow and epic presentation with use of delay on the guitar.
Have a listen here.
