In an interview with AOL Music News, Cornell discussed the possible directions this new solo album may go.
When I did the first [solo album] there was definitely a bit of surprise, because people expected it was going to be more in the vein of acoustic, and it wasn't, really. I feel like the songs for this second one may be more in that direction.
While the prospect of a new Cornell solo album is exciting, the singer has indicated that a release will not clash with Audioslave's forthcoming album.
This record comes out in September, and I don't really want the two to be fighting.
