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).
