THANKS to Mayor Giuliani's reign of rave wrath during the '90s, there ain't many clubs worth writing home about from New York. But while it's been tough for club owners to even get off the ground, a starved club scene has allowed for a handful of stalwart venues to reap the benefits of demand. Cue eight-year-old Cielo, with its roster that reads more like an A to Z of NY house quality than a list of residents - Francois K, Roger Sanchez, Willie Graff, to name but a few - still holding strong within a scene slowly but surely rebuilding itself.
