Proem's last album is more on the ambient side than the album before, which i prefer because of the additional glitchy sound.Plus,there's a second live set cd as well which is class.Socially Inept is also really good.
Kattoo's first album is my favorite and there's loads of variety inside like.Thing is,there is loads of aggressive breakcore along with the sweet atmosphere so if you don't fancy the breaks that much then go for the other two albums.By the way,you can download the albums on mp3 from free going to his website and leave a small donation in case he saved you from buying them without at least knowing
Stendeck has got two amazing releases and going for a 3rd one pretty soon.His last album Faces is beyond words really.The style is really close to some sort of atmoshperic neo-industrial mixed with IDMish breaks and a ton of melodies and it's so nicely done it actually sounds pretty psychedelic.
You can find samples and free tunes of them on LastFM,
Stendeck
Kattoo
Proem
Good luck with the hunt.
