Back Alley Brass Band isn’t Kansas City’s only New Orleans-style brass band. Yet the ensemble’s shrewd marketing strategies and its willingness to give audiences precisely what they didn’t previously know they wanted has made Back Alley Brass Band the most visible group of its type in the region. It’s no accident Back Alley Brass Band is making appearances at Kelce Jam and Boulevardia, two of the Kansas City area’s biggest music-related events this summer. Accordingly, the ensemble’s new EP Last Chance to Dance doubles as a sonic business card. The infectiously exuberant set of party music containing arrangements of Rick Astley and Miley Cyrus hits will almost certainly result in further high-profile bookings.
