For the truly devoted music nerd in your life, the EMP Pop Conference is like summer camp and your favorite college class rolled into one. Writers, professors and pop savants of all stripes gather to present papers and lectures on a huge swath of issues in pop music, from L.A. punk scenes of yesteryear to Kendrick Lamar and the feverish dance form of krumping. Fri.-Sat. at various times at USC and REDCAT. See empla2013.posterous.com to register.
