He’s one of the biggest rappers ever. And the Dedication Tour from Dwayne Michael Carter, better known as Lil Wayne, is about thanking the little people — playing the B- and C-cities he usually skips. If you’re keeping score, the New Orleans native has sold more than 100 million albums worldwide, making him one of the best-selling artists in history. And you may not get that many more chances to see him because the epileptic rapper has announced plans to retire at age 35 after the release of his long-delayed 13th album, “Tha Carter V” — noting that he plans to spend more time with his four children. Chief executive of Young Money Entertainment, Lil Wayne performs at the Richmond Coliseum on Thursday, Feb. 4, with special opening guest, trap and hip-hop duo Rae Sremmurd. The show starts at 7:30 p.m. Tickets start at $41.50 at ticketmaster.com or livenation.com.
