Recent Duke graduate and Cooler Than Me chart-topper Mike Posner plays a late-late-night gig at the Hard Rock.

New Found Glory, 7 p.m., $20 and up, Jannus Live, 16 Second St. N, St. Petersburg
Lance Armstrong, Napster and the Euro were hot topics in 1999. So was Coral Springs quintet New Found Glory and its emo-groundbreaking debut Nothing Gold Can Stay. But no one would have predicted the latter would be faring better than the others in 2011. NFG's playful, catchy tunes have in fact prevailed, helping to spur a generation of emo-pop-punk acts. The boys, now of parenting age, will play songs from the Blink-like new disc Radiosurgery, as well as oldies My Friends Over You and more. With Man Overboard, This Time Next Year, The Wonder Years, Set Your Goals. (727) 565-0551.
