Charlotte's jazz train keeps on rolling with a visit tonight by the pianist Robert Glasper and his band — the Robert Glasper Experiment. Truly a man of many worlds, Glasper successfully bridges the gap between "straight-ahead" jazz and more ... well ... "experimental" sounds — flavored by hip-hop, R&B, soul and more. This cat has worked with everyone from Bilal to Maxwell to Erykah Badu and Mos Def. So, missing his band's two-show performance — brought to you by Sai Music and hosted by Preston Miles (of V101.9 FM) — would be really dumb. $20-$25. 7 p.m. and 9 p.m. (Two shows.) Petra's Piano Bar, 1919 Commonwealth Ave. 1-877-993-8499. www.ez-tixx.com.
