The Trident Sam Houston Andrew III interview 2010. Sam left us in 2015. A really sweet person as you’ll soon see. Some wonderful insights into Janis Joplin, the late 60’s San Francisco scene, and Marin County. Miss you Sam. Thanks! Sam and I belonged to the Artista Gang created by Grateful Dead artist Alton Kelley. The Artistas (a local gang of Artist in Marin County) had one rule: There are no rules. See ya!
