The Greyboy Allstars are a San Diego jazz group created in the early 1990s. The founding members of the group were Karl Denson, Robert Walter, Chris Stillwell, Elgin Park, AKA Mike Andrews, and Zak Najor. The group was formed following the successful earlier collaboration of Dj Greyboy with Denson on the albums Home Cookng and Freestylin’, and originally featured Dj Greyboy playing tracks over the core bands instrumentals. The Greyboy Allstars mix soul jazz with a blend of hip hop beats, creating a unique style of music.
