Resonance's Slick! Live at Oil Can Harry's presents recordings made on September 5, 1975 at the Vancouver, British Columbia club Oil Can Harry's. Grant Green spent much of his final years on the road, but after he left Blue Note in 1974 he wasn't recorded much: just two other records, both studio sessions. Slick! represents his latest-known live recording, and it undercuts the conventional wisdom that the guitarist frittered away his final years.
