By Jeff Dayton-Johnson | KUSP – The Next Generation Jazz Festival – happening now at the Monterey Conference Center through Sunday night – is the twin to the Monterey Jazz Festival that happens in September. And raising money for jazz education is the explicit raison d’être of the MJF enterprise. One of the most rewarding components of attending the Next Gen festival is the exuberant vibe exuded by so many young jazz musicians in one compact space. You can see it on the performance stages, but you can also sense it in the jam and warm-up rooms and in the corridors. If you haven’t checked it out, there’s still time.
