Tchaikovsky’s Piano Concerto No. 1 “pushed the boundaries of virtuosity in its time,” says pianist Natasha Paremski, noting that it was originally considered unplayable but went on to become one of his most famous and beloved works. The Russian-born pianist, who has lived in the United States since she was eight, will perform the work this weekend with the Las Cruces Symphony Orchestra, under the direction of Lonnie Klein. Paremski came to the KRWG studios to talk with Intermezzo host Leora Zeitlin about Tchaikovsky, her career, how she handles nerves on stage, and more.
