Wednesday, July 2 @ Miller Lite Oasis, 10 p.m.
It was ironic that Belling chose Ludacris, of all artists, to wage war against, since by contemporary rap standards Ludacris is a pretty tame, often goofy figure. In the years since his last Summerfest appearance, Ludacris has filmed several more installments of the ridiculous Fast & Furious franchise, appeared as a rapping tube of toothpaste on “The Simpsons” and starred in a campaign for the non-profit 1-800-RUNAWAY crisis hotline. All that acting has slowed his music career somewhat, however. He hasn’t released a new album since 2010’s loopy Battle of the Sexes, though for years he’s been teasing a new album, Ludaversal, which may or may not see release this summer. Even if it doesn’t, Ludacris has a huge catalogue of boisterous pop-rap hits that should make July 2 a perfect night for hanging around the lakefront.
