Street Sweeper? (Morello and Boots Riley)

Street Sweeper is apparently Tom Morello and Boots Riley (of the Coup)

now. it seems a bit strange that this went under my radar, but you can get a hold of a couple songs from something free Reznor put out of unreleased music by Street Sweeper, NIN and Janes Addiction (2 songs of each).

Street Sweeper makes it pretty clear to me who should have taken Zack's spot in the in between time for RATM. Shoot.
