Every artist who records for Blue Note is part of a grand legacy, but pianist Paul Cornish is a torchbearer for several remarkable Blue Note legacies, all at once. Which makes You’re Exaggerating!, his powerfully lyrical trio debut for the label, a mission statement for Blue Note’s next generation. The new album features Cornish with the rhythm tandem of bassist Joshua Crumbly and drummer Jonathan Pinson, performing nine original compositions, most of them inspired by personal memories, reflections and idols. Helmed by a generous, uplifting bandleader, the trio chops up and reinvents the groove at will, and embarks on unforeseen detours. Cornish’s approach, in its even-keeled texture and shrewd harmony, is a sort of mastery that entices rather than merely impresses.
