Habitués of this space probably know of my esteem for Boston pianist and composer Pandelis Karayorgis, a musician whose rigorous explorations of the less frequented corners of jazz history have consistently yielded deeply original and compelling new sounds. He’s managed to revisit the work of pianists like Lennie Tristano, Herbie Nichols, Elmo Hope, Hassan, and early Cecil Taylor and bring back consistently fresh ideas in all sorts of contexts. Earlier this year he and Boston-based reedist Jorrit Dijkstra launched Driff Records—the label just added four new titles to its catalog, and they have me thinking that this might be the most exciting new jazz label in 2013.
