Whether playing a Gershwin song or Madonna's latest hit, pianist and singer Nathaniel Reed is always in tune with his audience. Perched atop the one-foot-high stage at the Piccadilly, Reed's baby grand piano faces the restaurant's main entrance. The entertainer, who can be heard weeknights from 7:00 to 11:00 p.m., often punctuates his many sets with greetings to new and familiar faces. No musician in Miami is more adept at handling a request than Reed, whose playlist pretty much spans all of the Twentieth Century. His musical experience also is wide-ranging. Although not inclined to speak of it, Reed is a polished veteran who has sung with Stevie Wonder, Patti LaBelle, and other notable talents. That breezy chatter you will hear between songs, accompanied by an irrepressible Louis Armstrong-like enthusiasm, is the product of years of hard work as an L.A. studio musician and a brief stint as a Caribbean cruise-ship piano man. Many is the patron moved to dance when Reed digs into his stockpile of R&B classics and begins swaying his head from side to side while stomping his feet to the rhythm. Saturday nights, beginning at 7:30 p.m., catch him at da Ermanno ristorante, 6927 Biscayne Blvd.
