Pittsburgh Symphony Principal Tuba, Craig Knox, talks with Jim Cunningham from his home in Mount Lebanon about the stay at home quarantine, delivery of dinner, teaching online, when we’ll have music at Heinz Hall again and Craig chooses the very solemn slow second music of the Bruckner Symphony No 7 as music to provide comfort during these troubled times. Manfred Honeck and the Pittsburgh Symphony had planned to record the Bruckner 7 this Spring until concerts were canceled.
