Jazz-Hop

Battles of the bands and MC battles consist of a certain amount of necessary rivalry among performers, who throw down for bragging rights and sometimes prizes. But the abbreviation for versus on the calendar at RecordBar (1020 Westport Road, 816-753-5207) implies more competition than actually found during the event called Mark Lowrey vs. Hip-Hop 2. Like its January predecessor at Czar Bar, this musical experiment won’t yield war but just musical collaboration as pianist Lowrey and other local jazz musicians improvise with freestyling local MCs. Cover costs $7.
