Under A Dying Sun had a fairly unique style with post-rock influence mixed in to a softer "screamo" sound that features sung and screamed vocals. I could compare them to scene mates Funeral Diner and contemporaries You & I; like You & I, Under A Dying Sun has a sound that is somewhat of a pre-cursor to the early 00s mainstream emo explosion, with a fair bit of rawness and creativity thrown into the mix.
