Tzimon Barto’s, Christoph Eschenbach’s and the DSO’s Bartók project is entering its second round: After Bartók’s 2nd Piano Concerto was performed and recorded in December, it’s time for No. 1 & 3 now. Recordings of both pieces have already taken place throughout the week; this Sunday Tzimon Barto will be performing them at the Philharmonie Berlin.
