Tomorrow (6) Underoath’s swan song comes out. The band’s greatest hits album, Anthology 1999-2012 will come out, and after a brief tour in January 2013 (which appears to be selling out quickly), the band . The greatest hits album also contains two new songs, “Sunburnt” and “Unsound.” You got a chance to hear “Sunburnt” last week, and here’s the other song. “Unsound” is more melodic than “Sunburnt,” and is reminiscent of Circa Survive than anything else. It’s a shame that the band is breaking up, because even though they were losing fans with every album, their music was going in a more interesting post-rock direction, and as one of metalcore’s progenitors moved on to new sounds, it would have been nice to see what they came up with next. Anthology 1999-2012 will be in stores tomorrow.
