As its name suggests, the Richmond, Virginia-based No BS! Brass Band is a horn-filled outfit that doesn't pull any punches. Bringing a New Orleans-style brass treatment to funk, R&B, soul and jazz arrangements, the 13-piece outfit fills out any stage it graces with trumpets, trombones and some punk rock attitude. Cuban jazz singer Dayme Arocena opens the show. This free concert is part of the 2017 Millennium Park Summer Music Series.
