Coroner
Anacrusis (BTW, you find all their albums, demos and some live-stuff for downloading here:
http://apogee.whack.org/~ken/index.html)
Sieges Even ("Life Cycle" - the music on this album might remind you of Watchtower´s "Control And Resistance" - and "Sophisticated"; "Steps" and "A Sense Of Change" are very good and technical - especially "Steps" -, too, but they aren´t thrash and definitely not death metal!)
Mekong Delta - "Mekong Delta", "The Music Of Erich Zann", "The Principle Of Doubt", "Dances Of Death"
Hades - "Resisting Success"
Toxik - "Think This"
Hexenhaus - "A Tribute To Insanity", "The Edge Of Eternity"
Atrox - "Terrestrials", "Orgasm" (Though there are also a few "soft" songs on these albums, most of the stuff is very technical and also "thrashy", especially on their latest album "Orgasm". In quite a lot of reviews of "Orgasm", Meshuggah were mentioned as a main musical influence. If you go to
www.atrox-web.com, you´ll also find some songs in mp3-format from each of their albums. Of the two from "Orgasm", "Flesh-City" is definitely the more representative.)
