Through the 1970s to the 2010s, from his recording and rehearsal studio, Red Door (venue), in the Chelsea neighborhood of New York City, Giorgio continued to nurture and mentor musicians. Following his relationship in the early 1980s with the band Material, he produced "Tonka Wonka Mondays" at the Bitter End, featuring three bands a night who were unnamed "mystery guests", and then had professional music critics dissect their performances during the break. At the end of each evening, a better-known featured guest would play their material backed up by "The House Band" led by composer / arranger Dave Soldier and featuring trumpeter Roy Campbell. Featured guests included Wayne Kramer, Billy Bang, Frank Lowe, and Dennis Charles. Giorgio was also a regular DJ at the club Tramps, introducing fans to an array of styles, including new African and experimental jazz music.
