Sudden Duo, a Boston based free jazz/experimental project, is a collaboration between Dylan Sherry on saxophones and electronics and Chris Southiere on drums. The duo’s debut album Frontier is a minimal and abstract approach jazz, with little to no harmonic accompaniment to Sherry’s lone horn. The “freedom” of Frontier is refreshing; the inherent confines of harmonic chord structures are nonexistent, which allows Sherry and Southiere to have a healthy and honest pursuit towards both everything and nothing, and whatever is in between. Frontier, in all of it’s imaginative and compelling space, is like listening to the great Albert Ayler sit in on a Sun Ra drum track. -Charley Ruddell
