Gregg most recently received an EMMY Award along with his band BLACKBOX and Cheap Trick guitar legend Rick Nielsen for their televised live performance.

Gregg's career began when he won the Slingerland/Louie Bellson National Drum Contest at the legendary Frank's Drum Shop in Chicago. Still a teenager, he landed the drumming spot with radio icon Steve Dahl. Along with Dahl and his band, Teenage Radiation, Gregg scored two hit singles, performed on Dahl's radio show, syndicated national shows, Emmy Award-winning television specials, feature film soundtracks, daily morning television shows, and live concert appearances.

Gregg has performed with the likes of Joe Walsh, Rick Nielsen, Cheap Trick, Steve Stevens, Billy Idol, John Entwhistle, The Who, Jack Blades, Tommy Shaw, Damn Yankees, and Billy Squier, among others, which led to his first major label record deal with the group, SIREN. Recording, videos, and tours followed when SIREN'S first album, All Is Forgiven garnered two hit singles, received heavy MTV rotation and received massive radio airplay.

Among the many highlights of Gregg's career is his Modern Drummer Magazine affiliation in which he was not only featured but also became a contributing writer. He is a clinician for many of the drum and accessory companies that have endorsed him throughout his career.

Gregg continues playing with national acts, recording, touring, writing, and gaining the respect of his drumming peers.
