It's been four years since the release of Rwake's impressive Voices of Omens, but the band is finally returning with Rest on Sept. 27 via Relapse Records. "It Was Beautiful, But Now It's Sour" is the lead-off track, a slow-motion, 12-minute song that begins with a serious on-your-knees Lynyrd Skynyrd-style guitar solo, which, according to a short email interview with vocalist CT, isn't the only one on Rest. The main riff remains largely unchanged throughout: It's a lumbering swamp monster surrounded by a lazy-eyed guitar melody and CT's searing vocals, which are somehow even more punishing than before. That said, CT's voice can transform itself into an emotional howl when the moment demands it. I love how the song unfolds in general — more rhythmic and psychedelic as the tempo progresses, perhaps a bit like the more percussive parts on Kylesa's Static Tensions.
