Bridging the gap between pop and classical is all in a day's work for pianist Jon Schmidt and cellist Steven Sharp Nelson. The YouTube sensations make surprising connections between traditional and modern compositions, expertly fusing Mozart with Michael Jackson, Beethoven with OneRepublic, and Vivaldi with the Frozen anthem “Let It Go”. What the duo accomplishes is beyond a mere mash-up. They go about it all with skill, passion and a palpable warmth in their playing, spurring each other on as the piano and cello dance together in perfect harmony.
