Whenever you come across the 92 Street Y’s Jazz In July series touted in print, you’re likely to see the word “exquisite” attached. Artistic Director Bill Charlap sculpts his programs and performer lists to stress the kind of grace that he himself brings to the stage when leading his piano trio. As usual, this year he peppers the repertory-slanted sched with vocalists. Ernie Andrews gives Duke a smooch, Ann Hampton Callaway glides through Sondheim and the mighty Kurt Elling embraces the mighty Frank Sinatra. Each will be bolstered by some of the city’s most sage improvisers. Vets Dick Hyman, Houston Person and Bucky Pizzarelli are part of an ever-changing cast that includes skilled boomers Matt Wilson, Ken Peplowski and Marcus Roberts. Mainstream jazz is full of finesse, and as the week-long fest puts its personal spin on history and unpacks the kind of splendor that tickles the button-down crowd, a distinct POV will emerge. Bet it’s exquisite.
