Dualtone's Absynthe and Aenimic.
Don't mind if I put one or two comments about your music and your chances of opening for NIN. Utterly no malice in my intention. Bro Aenimic bro, I think you know me well enough to know that I have the best intentions, man.
Ok, you are no doubt a gifted song writer and musician. But quite honestly, even if your sound is quite industrial ish, to put you on the stage as the opener for NIN would not be a good idea.
From what I can hear from your track on Myspace, you have more a Portishead, trip hop, dark ambient sound. NIN, however, is in-your-face, hard, fast and loud. People would expect to mosh and jump around with NIN music. Your music would be more suitable with a sit down chilled setting for a trip hop, electro performance. I see you more suitable to open for Portishead or Bjork.
I would suggest coming up with a few hard thumping songs that would get the crowd going if you want to open for NIN. I don't know if you have those songs in your repertoire or not. If you have, I would suggest rehearsing them to death. If not, I would urge you to start thinking about it.
Otherwise, the crowd will be cruel with you. The audience in general do not know who you are, hence they are far less forgiving. I'm sorry, but that IS the truth.
2 cents.
