iii by Darkest of Winter

iii by Darkest of Winter is a solid, heavy progressive rock song.  I love how the drums, bass and guitars all work together rhythmically and are ridiculously tight in performance.  I also enjoy how the song has definite separation when different parts of the song are introduced.  I enjoy a good surprise blast of guitars or the removal of that heaviness all of a sudden.  Even the vocals move from great melodies to metal growls.
