Some jazz fests bet the farm on stylistic focus; some let a wide breadth carry the day. File this year’s Blue Note Jazz Festival in the latter category and get ready for action. If you fully participate, you’ll be bouncing around town (and genres) for the next month. How else to describe a month-long confab that includes Bebel Gilberto and Kathleen Battle as well as Oliver Lake and the Rippingtons? Mainstream swing, old-school blues, swamp rock, classical refractions, and the city’s first all-women mariachi outfit — the BNJF curators aren’t sweating the orthodoxy, and that alone is rather refreshing. Icons are invited, of course; saxophonist Lee Konitz, drummer Roy Haynes, and pianist Abdullah Ibrahim still have the power to amaze. You’ll need to sketch your own must-see list, but be wise: That Bad Plus-Joshua Redman gig has to make the cut.
