Smooth jazz, roots-infused bluegrass, African rhythms, Indian tabla melodies. No, it’s not an explosion in the world music section of you local record store–it’s an attempt to define the sound of Project Mastana , a popular local group with global style. The contagious quartet doesn’t just redefine diversity; they’re also really good. They’re playing Saturday, July 19, at 7:30 p.m. at NCMA’s Museum Park, a night of Indian flavor at the entertaining outdoor mainstay. Following the show at 9 p.m. is the subcontinent’s 2001 hit Monsoon Wedding (Vasundhara Das pictured above), a sensationally popular and critically acclaimed cold-feet romantic comedy in Hollywood and Bollywood alike. It’s a fitting coda for a flavorful evening. Admission is $9, and $4 for children (though the film is rated R for language).
