Mark Lanegan is the soft-spoken elder statesman of the '90s Seattle grunge scene. Marc Maron talks with the former frontman of Screaming Trees and finds out how Mark went on to collaborate with a wide variety of artists, from Guns N' Roses to Belle and Sebastian. But first, singer-songwriter Mac DeMarco brings his laid-back Canadian rock vibe to the garage as he releases his third studio album and helps answer a puzzling question: Why does Marc like his music so much?
