He performs regularly both as a solo artist and as a sideman, tours widely all over the country, writes scores for films, plays, radio, and television, and has produced several well-received albums of original instrumental music. Ben’s performances are at once dazzling and intimate, the music both delicate and commanding. Show $20. Dinner & Show $40. BYOB. Reservations required for dinner and recommended for the show.
