The Telluride Jazz Festival may be entering its fourth decade, but the mountain-town hootenanny shows no signs of slowing; if anything, the festival is growing more open-minded as it ages. Though it’s continuing the time-honored tradition of inviting the finest jazz musicians to Telluride's Town Park, 500 East Colorado Avenue, for three delightfully jazzy days, the organizers are also offering "Jazz After Dark" showcases scattered throughout music venues downtown. This year's festival lineup includes New Orleans-inspired funk and jazz from the Cha Wa Mardi Gras Indian Band and the Hooligan Brass Band, but many of the headliners — including Mavis Staples, Macy Gray and the Funky Meters — hail from R&B, funk and soul. The weekend of fun and funk starts at noon on Friday, August 4. Single-day tickets start at $60, and three-day festival passes at $160. Visit telluridejazz.org to buy yours and see the full schedule.
