Pianist Behzod Abduraimov returns to Heinz Hall to make his debut with Juraj Valcuha in the Prokofiev Piano Concerto No. 2. They’ve recorded together in Italy for Decca but never given a live concert until Pittsburgh. Is playing with a mask fun? No. Especially during this concerto, which requires heavy lifting but he’s managing. Behzod talks all about Prokofiev and his recent recordings of Rachmaninov’s own piano in Lucerne, Switzerland, where he toured the villa Rachmaninov.
