Since his marathon performance of Bruch's Kol Nidre, an original arrangement of Ora No Omboko and his own Bad Rap for Violin and Chamber Orchestra with the Colorado Symphony on a borrowed Stradivarius in 1996, Gregory Walker has become known as "one of Colorado's most adventuresome musicians" (Denver Post). Walker has been featured with American orchestras such as the Cleveland Chamber Symphony, the Breckenridge Festival Orchestra, the Boulder Baroque Festival Orchestra, the Jefferson Symphony, the Four Seasons Chamber Orchestra, the Centennial Philharmonic, the Ft. Collins Symphony, the Loveland Chamber Orchestra, the Westminster Symphony, Oregon's Yaquina Chamber Orchestra, and abroad at Great Britain's Lake District Music Festival, Cuba's Encuentro Musial de los Americas, and the Spoleto Festival in Italy.

Concertmaster of the Boulder Philharmonic and Associate Professor of Music at the University of Colorado at Denver, Dr. Walker is also equally at home on acoustic and electric instruments having recorded Kaleidoscope: The Music of African American Women with pianist Helen Walker-Hill and appeared with pop star Lyle Lovett. Recordings available on CRI, Orion, Leonarda, and Albany labels feature the "silky violin tone and beautifully calibrated phrasing" described by the Newark Star-Ledger in its review of his latest release: Pulitzer prize-winning composer George Walker's Poeme for Violin and Orchestra.

Gregory Walker has completed the production of the Electric Vivaldi CD, an electronic reworking of Vivaldi's beloved Four Seasons. The Four Seasons contain musical illustrations of the composer's poems that lend themselves to the illustrative sound effects possible with electronic technology, and Walker's electronic interpretation at the Colorado Music Festival in 2002 generated substantial interest within the classical recording industry.

It's available for purchase at the Boulder Philharmonic Box Office.
