However, the growth of WZUM and the jazz scene in Pittsburgh is starting to bump into some limits.

WZUM’s Jazz Central Calendar is increasingly comprehensive and we try to make it accurate as possible - putting in addresses, times, the names of venues, performance times, leaders and other players. With 260+ Jazz Events in July - we are hitting the limits of the calendaring system!

Hear what we’re keeping up with - including

NYO Jazz, led by Sean Jones - at the August Wilson African American Cultural Center, Tuesday, August 2nd. BNY Mellon JazzLive - featuring Kenny Blake August 2, 5-7pm; Jazz at the Highland Park Reservoir on Sundays in August - 5-7pm, including John Shannon and Fourth River on August 7; plus, finishing July - sounds include the Hill District Arts Festival on Centre Avenue, including Anita Levels, Tubby Daniels, Tony Campbell, Jessica Lee/Mark Strickland/Hugo Cruz, and the Roger Humphries Big Band.
