Track for the stack: The formidable 'Letter For Paul' an epistolary jazz message to the late Head Hunters great Paul Jackson is today's early-morning listening, looking like an all-day on as well, choice from John Patitucci, Chris Potter, Jon Cowherd, Marcus Gilmore and Rogério Boccato. Possessing a 1970s sublimated jazz-funk feel with a big impressive solo from Potter part of the recipe, ex-Vijay Iyer trio drummer Gilmore from the classic VIT chops up the beat to make choicest filet mignon. Cowherd on neat sounding Rhodes-type electric piano comps like he never wants to switch off and Patitucci's riff on bass guitar at the heart of the tune (there's also a little tasteful overdubbing) and what it's all about as a Jackson homage keeps it interesting even to the fade at the end.
