Great Life founders Colby Beserra and Brian Schwab are seriously plugged into the Chicago music scene, so they can really tweak the entertainment to your specific taste. You can turn to them for everything from a string quartet to a seven-piece band, and they also represent some excellent organists and pianists. Colby and Brian are amazing performers and songwriters in their own right: if your event can handle a large ensemble, make sure to book their personal band, The Party Faithful.
