ArtHamptons goes even more international

WHAT Now in its fourth year, ArtHamptons has become one of the nation's top summer fine art fairs. More than 10,000 art shoppers and browsers are expected over the three-day event in a 50,000-square-foot modular space in Bridgehampton. The geographic scope has been widened this year to a dozen countries -- the United Kingdom (with 10 galleries), Spain, Germany, Israel, Russia, Japan, China, South Korea, Argentina, Mexico, Canada and, of course, the United States. Though it's a temporary space, the "museum" is air-conditioned. (The galleries insist. When you represent the likes of Anselm Kiefer or Robert Rauschenberg, you don't want the art to sweat.) Receiving ArtHamptons' lifetime achievement award this year is abstract expressionist Mary Abbott, a descendant of President John Adams and Confederate Gen. Robert E. Lee. She lives in Southampton. The arts patron of the year award is shared by co-founders of Rush Philanthropic Arts Foundation: hip-hop impresario Russell Simmons and his brother Danny, a painter.

WHEN | WHERE 11 a.m. to 7 p.m. Friday and Saturday, 11 a.m. to 6 p.m. Sunday at Sayre Park, 154 Snake Hollow Rd., Bridgehampton

INFO $15 per day, $25 for three-day pass; arthamptons.com, 631-283-5505

Music: Long Island Museum concert

WHAT The Long Island Museum presents a concert of popular works by 19th century American composers performed by a brass-and-string duo from Stony Brook University -- James Hubbard on trombone and Zach Goodman on banjo. The program amplifies both the current "Power of Music" exhibition at the museum and its most important collection -- paintings by William Sydney Mount, a 19th century Setauket artist whose best known works, such as "Dance of the Haymakers," are on a musical theme. "The Power of Music" explores how folk songs, gospel and classical works influenced American history before the advent of mass media.

WHEN | WHERE 2 p.m. Sunday, Long Island Museum of American Art, History & Carriages, 1200 Rte. 25A, Stony Brook. "Power of Music" exhibit open 10 a.m. to 5 p.m. Fridays and Saturdays, noon to 5 p.m. Sundays through Sept. 4

INFO Concert free with museum admission: $9, $7 seniors, $4 students; longislandmuseum.org, 631-751-0066
