This week, Features contributor Mike Nikolich speaks with saxophonist and composer Mars Williams, the force behind Liquid Soul and previous member of The Waitresses and The Psychedelic Furs. They discuss his illustrious decade- and genre-spanning music career, regular stops through the 90s and 2000s at the Elbo Room and Double Door with Liquid Soul, and his annual tradition of releasing a Christmas series of songs originally inspired by playing his sax along with recordings of John Coltrane.
