Don't look now, but there are white Greek gods balancing blue balls in Chelsea. That's courtesy of American artist Jeff Koons, famous for his balloon animals made of stainless steel. The show is at David Zwirner gallery, and it's just one of several mega-shows happening in galleries this month.

Koons also has a show with his shiny phalic figures at the Gagosian, which has represented him for many years. Bloomberg News reporter Katya Kazakina says both shows, and others like the one by American sculptor Mark di Suvero at Paula Cooper Gallery are evidence that Chelsea galleries are showing their "big guns" this spring.

"Big art brings big crowds, and draws a lot of attention," she said. "Also, all those shows opened in May and May is a huge month for New York galleries because that's when the auction houses have their big impressionist, modern and contemporary art sales."

Kazakina also recommends some small shows though, including by Los Angeles based ceramic artist Shio Kusaka at Anton Kern Gallery and by American painter Thabita Vevers at Lori Bookstein.
