One of my personal issues with doom is that it just all sounds very similar and repetitive. I was expecting much of the same when I put on 'The Year Zero Blueprint' by Until the Sky Dies but quickly had my thoughts eradicated and thrown back in my face. While the band utilizes the doom formula of slow, sludgy pacing they also throw in some curve balls to mix things up. The Pink Floyd-esque feel of "VI" was a big surprise and a really welcome change. Little nuances like this are throughout the whole album and it helps keep things sounding fresh and engaging without falling into stagnation.
