Moxiebeat is pretty incredible. It's downtuned and heavy but with an underlying hint of melodic nature. Even among their most chaotic moments there's an excellent melodic sensibility that runs in the background.
In terms of tempo and style Moxiebeat can really mix things up, going from a totally chaotic attack to a more subdued, melodic approach without any issues in the transition. There's some excellent musicianship happening throughout all four songs, keeping even the most straight forward punk influenced parts interesting and unique.
