The National Repertory Orchestra continues their jam-packed summer season Saturday evening with a presentation of Aaron Copland’s “Symphony No. 3,” specially dedicated to the memory of a long-time supporter of the orchestra, Diana Knapp.

The concert, which will be held at the Riverwalk Center in Breckenridge at 7:30 p.m., will also feature guest musician Jeanette Aufiero on piano to play Piotr Ilyrich Tchaikovsky’s “Piano Concerto No. 1 in B-flat Minor.” Aufiero is a Juilliard pre-college and Manhattan School of Music graduate, and is currently pursuing her Artist Diploma at Cleveland Institute of Music under Antonio Pompa-Baldi. Most recently, she won the New York Concert Artists 2012 Rising Artist Concerto Presentation.

“I am passionate about music, especially piano, and I cherish opportunities to express my love and passion through performing. I always hope that my passion is portrayed as I play. I hope that as I play listeners will be able to understand the story and passion behind the art,” Aufiero said about her performances.

The concert ends with “Symphony No. 3” by Aaron Copland. The work features Copland’s distinctive Americana style heard in some of his previous works, like “Rodeo,” although the symphony does not directly use folk material. Instead, he borrowed from himself rather than other sources, incorporating his “Fanfare for the Common Man” as a central theme.

“Copland’s ‘Symphony No. 3’ is such a thrilling work; this is probably the piece that I look forward to the most out of the entire season,” 35-year music director for the orchestra Carl Topilow said.

Knapp recently passed away after battling five years of brain cancer. Ken Knapp, Diana’s husband, continues to support the orchestra, particularly through the Community Link program.

“The music tonight will bring closure to the full but all too brief life for my wife,” Knapp said. “I had never met anyone more spirited or braver in the face of adversity than she was. Her fortitude and drive towards her personal goals were amazing.”
