Geggie performs in the Ottawa-Hull region as a freelance double bass player and teacher. He is best known for running the late-night jams during the Ottawa International Jazz Festival, and for his invitational series (in its tenth year as of 2010-11) of jazz concerts which run at the National Arts Centre Fourth Stage in Ottawa. In the latter series, Geggie invites jazz artists from across Canada and the world to play with him in one-time-only groups, in which they perform material written by each of the artists, as well as jazz standards. Geggie is a member of 'The Geggie Project', with pianist Marilyn Crispell and drummer Nick Fraser. Most recently they performed at the Guelph Jazz Festival on September 11, 2009. The concert was recorded by the Canadian Broadcasting Corporation (CBC) and broadcast on The Signal on October 3, 2009.
