At the moment, Celldweller, Jenarium, The Birthday Massacre, Blue Stahli, Collide, DeadStar Assembly, Gary Numan, Halo In Reverse, ISCINTILLA, NIN, Skingame, some occasional Zeromancer.
The only one I know from that list is NIN, which is quite obviously my favorite band and the most commercialized of any industrial act. I only know Gary Numan through Trent's cover of "Metal". I'll definitely have to give some of these a listen, I'm always ready to check out new cool music.
Combichrist is a highly commercialized act as well, and I would even go as far to say that they've reached NIN's status within the realm of EBM. Some other ones that I have on my iPod are Covenant, Artosis, KMFDM, Dracul, Gravity Kills, Stabbing Westward, kidneythieves, Funker Vogt, Frontline Assembly, Front 242, Skinny Puppy, Ministry, Rammstein, Marilyn Manson, Orgy, etc.
I'm afraid I've only gotten mostly the mainstream dose of industrial, so I'm trying to dig deeper into the underground. The opening act for Combichrist was
very interesting. A group called "Ivardensphere": their set was 3 sets of congas/drum sets with a dj/synth, and the 3rd conga drummer kept jumping back and forth between the synths and the drums. Absolutely incredible.
The 2nd act was a group called "Aesthetic Perfection". Their set was a vocalist, drummer, and dj/synth. They sort of remind me of another group I've heard online called "Suicide Commando".
