CA poster here. Deak is def not on the album. Talked to deak at the AC/eric copeland dj set in brooklyn last fall. Deak seems pretty messed up on drugs honestly, not sure if it those drugs are psychs or downers, but he was toasted. He said he was "so close" with the solo album. As a past donor to his africa project, I was skeptical and just said "sure man, that sounds really cool..." and walked away. He winked at me in this weird way that I can't really explain, and then sauntered off whistling the high pitched vocal part from fireworks.
