Throughout his life and career, Christian Howes has thrived on venturing outside of his comfort zone. He’s taken the violin into the relatively unexplored territory of modern jazz, combining classical training with soulful expressiveness; and he’s been on the vanguard of digital-age entrepreneurship with his online classes and virtual string orchestra. For his new CD — Southern Exposure” — Howes takes another unexpected turn, this time into the realm of Latin music, exploring a diverse range of repertoire from Brazil, Argentina, Cuba and Spain. His chief companion on the journey is French accordion master Richard Galliano, buoyed by the smoking rhythm section of bassist Scott Colley, drummer Lewis Nash and pianist Josh Nelson.
