Apparently Radioactive Man will NOT be appearing on Saturday (however you can still catch Cybrid and Broker/Dealer):

"Due to circumstances beyond our control, Radioactive Man will not be appearing"

[from dr] Get out the Geiger counters! Nuclear-powered robots will want to head over to 132 Eddy St. this Saturday night to hear Radioactive Man (Two Lone Swordsmen's Keith Tenniswood) along with Cybrid and Broker/Dealer. More info at blasthaus.com.
