Horn player L. William Kuyper says that an orchestral player who steps out in front to be a soloist has to “be a leader, and give forth his or her own interpretations,” instead of adapting to that of the conductor. “And we must honor his ideas,” says conductor Marianna Gabbi, who will lead the New Horizons Orchestra in several works this weekend, including Mozart's Horn Concerto No. 3, with Kuyper as soloist. Kuyper retired from his position as horn player in the New York Philharmonic several years ago, and has been making music in Las Cruces ever since. The two musicians came to talk about their collaboration, the music on the program, and Mozart’s long-time friend Joseph Leutgeb, for whom he wrote four horn concertos. The concert will also feature Lizandro Garcia, from Juarez, conducting Mozart’s Symphony No. 25, and the Borderland Bones Trombone Quartet.
