Pittsburgh jazz legacy Billy Strayhorn would have turned 103 on Nov. 29. To celebrate the composer’s important strides in the jazz world — Strayhorn is known for his work with Duke Ellington — Kelly Strayhorn Theater brings local jazz icons to perform in honor of the venue’s namesake. This year, percussionist extraordinaire Roger Humphries and The RH Factor plan to take audiences on a musical exploration that explores Pittsburgh’s rich contributions to jazz. Before the show is a VIP reception in Hotel Indigo that will benefit the Strayhorn Legacy Fund, which supports youth and family programming at Kelly Strayhorn Theater.
