In December 2014, the St. Lawrence String Quartet performed at the Library of Congress’ Stradivari Anniversary Concert. Before the performance, we talked with ensemble co-founder and violinist Geoff Nuttall about creative failure and the importance of risk-taking. While discussing one of the pieces they would be playing—Mozart’s String Quintet in G minor, K. 516, with guest violist Hsin-Yun Huang—Nuttall shared his thoughts about the piece, and how even Mozart worried about failure sometimes. Here's an excerpt of the talk and of the music, which we caught during a pre-performance rehearsal.​ Read the full interview with Geoff Nuttall.
