Due to Art Basel, the eye of the art world is on Switzerland right now. But don't fret. There are two major art festivals beckoning from the boroughs -- Queens Art Express and Brooklyn's Northside -- that should keep your schedule stocked with art, film, and music. There's also a rockin' opening at Agnès B., a whisky-and-bagpipe homecoming for artist Mark Selinas, and four centuries of Caribbean works at Queens Museum of Art. All this and more, on this week's art roundup.
