In addition to his wide ranging teaching credentials, Gary has been a featured Blues harmonica instructor for Blues enthusiasts of all ages at festivals and events including: Augusta Heritage Center's Blues Week, Tremblant International Blues Festival, Telluride Acoustic Blues Camp, Winter Park Blues Festival, Riverfront Blues Festival (six consecutive years), Billtown Blues festival, Cruisin’ for a Bluesin’ Blues Cruise (consecutive years), the California Traditional Music Society's Summer Solstice (consecutive years) and Equinox Folk Festivals, John Gindick's Harmonica Jam Camp, the 2007, 2008 and 2011 Folk Alliance Conference, the Stax Music Academy in Memphis, the Americana Music Fest and the Colorado Blues Society. He was recently selected as the first harmonica instructor to teach at the Pinetop Perkins Foundation Master Class.

Gary is a Blues educator that goes beyond just an extra mile. Particularly noteworthy are his recent efforts that were instrumental in achieving a Western Hemisphere Record, teaching nearly 5,000 folks in Houston’s Minute Maid Ballpark in an event produced by 2010 KBA Award winners “Pocket Full of Soul” (the harmonica documentary film in which Gary is a featured artist). The Blues song that Gary transcribed and helped teach was one that he uses regularly in his workshops; Bo Diddley’s “I’m a Man”. The event generated much media attention and was televised to hundreds of thousands in sports highlight segments. Consequently, the event drew massive public attention to Blues Harmonica. More importantly, it also served as a spark for many of all ages to interactively play a classic song in the genre - helping to keep it alive and celebrated on a large scale.
