The new gallery space LX (that’s Roman numeral for 60) is aiming to bring the boundary-pushing, interdisciplinary, and after-hours spirit of the downtown art world to the avid collectors forty blocks north. “60th Street is the most vibrant block on the Upper East Side,” founder Louis Buckworth said. He added, “There has been a real renaissance in these few block in the last three to four years.”

LX, a new gallery based on New York’s Upper East Side, has opened its doors at 36 East 60th Street. Founded by Louis Buckworth and directed by Cecilia Weaver, LX kicked off its programming on January 10 with a group show titled “I Don’t Believe in Art, I Believe in Artists,” curated by Jen DeNike. Buckworth said in a statement, “Being an art collector in the real estate business, I’ve long dreamed of combining my two passions. LX represents my desire to reinvigorate the great tradition of artists and patrons on the Upper East Side.”
