can someone recommend me some albums by any of these bands?
Aghora - Only have their self-titled debut so far. New one coming out next year. Complex prog with female vox.
Behold... The Arctopus - Only have 2 EPs, each with 2 songs - "Nano-Nucleonic Cyborg Summoning" and "Arctopocalypse Now... Warmageddon Later". Both EPs are available on 1 CD now. Obviously, they'd have to play some cover tunes or unreleased material.

I like Arctopocalypse and don't care for Nano-Nucleonic. Instrumental tech metal.
Canvas Solaris - 1 EP and 2 albums, and a new album coming in early 2007. I like their heavier, frenetic material the best so I prefer the EP, Spatial/Design. If you're more into ambient stuff check out their later albums, Sublimation and Penumbra Diffuse. Instrumental eclectic metal, sometimes tech, sometimes ambient/world music.
GracePoint - Science of Discontent is their only official release. I have had their Full Circle full length demo for years now though. Both are awesome complex prog with unique vocals for the genre (cross between Armored Saint and Stone Temple Pilots).
Protest the Hero - Kezia is their second album, and it rules. It has some metalcore to it though, so don't bother unless you're into that.
Spastic Ink - Ink Complete is my fave of the two. Instrumental tech metal made by the guitarist from WatchTower.
Spiral Architect - A Sceptic's Universe is their only disc. Brilliant tech metal with great vocals from the Manitou singer (vox similar to Psychotic Waltz).
Twisted into Form - Then Comes Affliction to Awaken the Dreamer is their only disc. Have been described as Spiral Architect meets Fates Warning circa Perfect Symmetry.
Unexpect - In a Flesh Aquarium is their new one, and it's a fun, constantly changing rollercoaster ride through a demented circus. Death vox and clean female vox. Violin. Heavy riffing craziness. You really just need to hear them for yourself.
WatchTower - Control and Resistance is brilliant, classic tech metal. High pitched vox by the singer for Hades turn some off.
