The Symphony draws outstanding instrumentalists from a 100-mile-radius, and features regionally, nationally, and internationally acclaimed guest artists. Though Galesburg is a small town, the Symphony presents a quality of music more common in a much larger city, with performances broadcasting often on public radio stations, helping the Symphony reach a wider geographical area.
In 1997, the Symphony toured Spain, with sold-out performances in Lleida, Reus, Girona, and at the world-famous Palau de la Musica in Barcelona. The following year, composer Eric Speier selected the KGS over eight other orchestras from across the United States and Europe to perform his film score for a Columbia Tri-Star Home Video. In 2001, as part of its 50th Anniversary celebration, the KGS performed The Nutcracker with the Saint Louis Ballet.
