If you don't know Wiz Khalifa, Mac Miller or Big K.R.I.T. -- the grandstand's first all hip-hop lineup since Vanilla Ice in 1991 (and thus maybe the first, period) -- then you have never been to Soundset. All three rappers made their first big local impressions at the Twin Cities' annual hip-hop festival. The Pittsburgh-bred, Minot, N.D.-born Khalifa broke big a year after his Soundset set with 2010's No. 1 hit "Black and Yellow." About to release his second album, "O.N.I.F.C.," the real-life Cameron Thomaz is quite a lively and tight rapper on stage, despite his hazy hemp-headed image. His hometown pal Miller, 20, is also a fireball but can take the bratty party-rap gimmick too far. Mississippi-bred K.R.I.T. killed it at this past year's Soundset and has one of this year's best Southern-fried rap albums, "Live From the Underground."
