Gene Bertoncini (Bar Henry, 90 W. Houston St., 646-448-4559, Mondays at 7:30-10:30). After a distressingly long hiatus caused by the closing of Le Madeleine three years ago, the great jazz guitarist now has another regular New York gig. If you don’t know Bertoncini’s playing, go here and marvel at the liquid tone and supple romanticism of his solo style. Then go to Bar Henry and hear him in person–often (TT).
