GCS grew up with the concert industry. GCS was there when George Benson sang “Masquerade” for the first time, Grandmaster Flash scratched the first vinyl, and the last time Steve Goodman sang “A Dying Cub Fans Last Request” (recorded for Greatest Hits – Live). From the 70’s simple R&B club bands, the 80’s techno pop bands, to big band swing and hip hop in the 1990’s, the 21st Centuries’ biggest arena acts and music festivals, we’ve done it all.
