In this first proper episode of the Sumner Files, Adam talks with Mark Cunningham, the bass player in Mars and one of two surviving members of the band. Mark also played brass instruments on John Gavanti, and that record was released on Mark's own label, Hyrax. Mark has had a long career since then, with bands including Don King, Raeo, Convolution, Bestia Farida, and Blood Quartet, as well as two recent solo albums, Odd Songs and Blue Mystery. Adam and Mark talk about Mark's life and career trajectory, including a detailed chronology of Mars from start to end. You can find much more about Mark's music and other works at markcunningham.cat and much of the music itself at markcunningham1.bandcamp.com. This conversation was recorded in July 2024.
