“Be a Rock Star” is a karaoke night fundraiser in support of Tampa Bay Derby Darlins, the area’s own roller derby league. Pay the measly admission fee, get good and juiced up, pick the song you want to slaughter, contribute $1, and do your thing with Cowboy Mafia, DJ Robb Smith, the Rancid Polecats or Dangerflight providing back up. Hopefully, they’ll play loud enough to drown you out. Fri., Nov. 28, 10 p.m., Crowbar, 1812 N. 17th St., Ybor City, $5.
