Rivers of Nihil - Temporality Unbound. This is brutal technical death metal with impressive musicianship, and a few excellent solos. The occasional use of keyboards adds atmosphere, but then it's quickly back to being brutal again. Lots of progressive gymnastics, but without overdoing it. Also, the nice crunching guitar tone and the harsh, almost-hardcore-but-not-quite vocals keep everything grounded as No Clean Singing puts it. Check it out.
