The Dartmouth Wind Symphony will celebrate the life and work of composer and arranger Vaclav Nelhybel in a concert titled "A Composer's Life: Vaclav Nelhybel," tonight in Spaulding Auditorium. The Wind Symphony is a campus student ensemble that performs classical and contemporary music on campus and throughout New England. The concert will feature French horn artist Daniel Culpepper as the guest soloist in "Concerto for Horn and Sixteen Instruments," a work written for him by Nelhybel in 1983. Other works in the program will include "Chorale," which Nelhybel based on a medieval Bohemian chant that was born out of fear of the plague. "High Plains March," which will also be featured, is the only work by Nelhybel that can be categorized as a march. Some other pieces in the evening are Nelhybel's arrangements of pieces by Smetana, Monteverdi and other composers who influenced his work. Director of the Wind Symphony Max Culpepper, the father of Daniel Culpepper, will join Gary Corcoran of Plymouth State College, Douglas Nelson of Keene State College and Stanley Hettinger of the University of New Hampshire.
