As the sun went down over Central Park last night, the music was just getting turned up atop 1280 Fifth Avenue, where the Harlem Blues & Jazz Band was playing for guests on the rooftop terrace of One Museum Mile. The event was a kick-off celebration for the fall sales season at the luxury condominium building, which is now 40% sold and in-contract. We’ll have more details on the event and the latest news on the building next week, but for now we wanted to give you a glimpse of this legendary band of musicians, which first formed in 1973. And for those curious about One Museum Mile, there’s an open house this weekend from 12-3pm on Saturday, and 1:30-4:30pm on Sunday.
