LP should work with John Feldman. He did The Used's last album, as well as Escape The Fate's latest album and a bunch of other good bands, I think he worked with Atreyu too but I could be wrong. I think he would be a good fit for LP actually, the only concern I would have is that he tends to make bands less heavy, and I want a heavy ass LP album but we probably won't even get any heavy tracks this time around.
