Scoremore presents a release party for up-and-coming local rapper Doughbeezy for his new CD Blue Magic at Warehouse Live tonight ($15). The album features Dough's collaboration with Killa Kyleon, "F*ck You," which should not be mistaken for the Cee-Lo song of the same partially censored name. Watch the Houston Press music page in a couple of weeks for a story on "The Beast of the Southeast." Dough is giving away Blue Magic on his Web site.

A long list of local musicians, vaudevillians, comedians and more - some of them U of H students - perform at this weekend's annual Frontier Fiesta, which started Thursday night. (Doughbeezy's in there somewhere tonight, before his own CD release; so are the Niceguys.) It's totally free. See more information here.

Local alt-metal veterans Downfall 2012 headline Live Nation's That Big Metal Show tonight at the new Bayou Music Center, or the old Verizon Wireless Theater.
