With a few exceptions, the composer and social media influencer’s walls are bare. But who needs art when you have Liberace’s piano?The test of a first-rate intelligence, F. Scott Fitzgerald wrote, is the ability to hold two opposing ideas in mind at the same time while still managing to function.Chloe Flower (neé Won), the composer, pianist and influencer can relate: For the past three years, she has lived happily on the 63rd floor of New York by Gehry, an apartment tower in the financial district. And yet, she is also “really scared of heights.”But Ms. Flower, 35, the spirited, couture-clad presence at the keyboard when Cardi B performed “Money” at the 2019 Grammys, is nothing if not pragmatic. The music videos she shoots in her two-bedroom rental — the cityscape a key element — have helped her build a robust following on social media.“I took one for the team because of Instagram,” said Ms. Flower, whose repertoire includes hits by the likes of Drake, Nicki Minaj and Kendrick Lamar, played in the style of Bach and Beethoven — or, as Ms. Flower characterizes it, pop-sical. “But really, when you look out the window and straight across, you don’t have a sense of depth.”Chloe Flower was born Chloe Won, but was nicknamed Flower as a child, and flowers are always close at hand. An arrangement sits atop the bedazzled Baldwin concert grand, a loaner from the Liberace estate.Katherine Marks for The New York TimesChloe Flower, 35Occupation: Composer and pianistSpecial Delivery: “During Covid, I was buying cabinets online from Restoration Hardware, and I forgot to remove the bed I had put in the shopping cart. When the guys from the shipping company arrived, they said, ‘We have your bed,’ and I said, ‘What bed?’ So now I have an accidental blue bed.”Also, up there in the stratosphere, Ms. Flower is at a considerable remove from ambient street noise. She was, thus, able to record most of her self-titled debut album at home. It’s due out July 16.Location. Location. Location. So goes the real estate mantra. To which Ms. Flower responds: Who cares? Who cares? Who cares? “Whenever I’m looking for an apartment, I’m never concerned where it is, because I’m either working from home or working in a studio,” she said.“I prefer certain areas of New York, of course,” added Ms. Flower, who previously rented in Union Square and Gramercy Park. “But New York has everything everywhere. Same with Los Angeles.”In fact, she was living in L.A. when she and her boyfriend, Michael Sepso, a New York-based entrepreneur, decided to move in together and began looking for suitable quarters.It was the musician Questlove who introduced his pal Ms. Flower to New York by Gehry. He is a tenant, “and when I saw his place, that was it,” she said. “I was, like, ‘Wait. Hold on. The view.’ I was so excited.”One attraction was the bay window in the living room, which “makes the apartment feel much bigger,” Ms. Flower said of the space, which is almost 1,400 square feet.Much of it is ceded to the Steinway Spirio|r, a piano that can record and play back performances, and to a Baldwin SD10 concert grand with a transparent lid and a cladding of hundreds of glass tiles, a loaner from the estate of Liberace to add flash to those Instagram videos. The man known as Mr. Showmanship often took it on tour. “Aesthetically, it doesn’t look like any piano you’ve ever seen. It’s really, really cool,” Ms. Flower said.“I love Liberace,” she added. “I know he’s not a traditional classical pianist, but he used his flair and drama and passion to break into the mainstream pop world. I like to celebrate him.”Ms. Flower loves having friends and family visit. Pre-Covid, everyone in her orbit referred to the second bedroom, now an office-slash-workout area, as Hotel Chloe. But visitors don’t have too many places to perch. There are no easy chairs, and Ms. Flower ditched her purple Ligne Roset sofa two years ago, when the Liberace joined the Steinway.“It was beautiful,” she said. “But when I had to choose between a second piano and a couch, it was, like, ‘A piano, of course.’”To be sure, there are other things in the living-and-dining room: a wood dining table; a teak tree-trunk console, a Yamaha keyboard, a pair of sculptural bookshelves, a vase or three of flowers, and many white candles. Ms. Flower buys them by the dozen from Amazon, lighting and shuffling them around as the spirit moves her.“I love their glow. I like the way they look when they’ve burned down,” she said. “They’re romantic and I think they set a mood, especially at night against the city lights.”But the décor must always serve the music. “When I’m composing, I don’t like to have a lot of distractions, and clutter is distracting,” she said. “I like the space to be clear, so I feel I have a clean slate.”Ms. Flower wrote her latest composition, “Tamie,” on the Steinway.Katherine Marks for The New York TimesConsequently, with the exception of a gilded mirror and a TV screen that doubles as a canvas to display digital art, the walls are bare. So are most surfaces.The annotated piano books and sheet music that Ms. Flower has had since childhood — “if there were a fire, I’d take them out first” — were briefly on a shelf in the living room.“But they just looked a little messy, a lot of loose paper,” she said, so she consigned them to a Restoration Hardware cabinet in the couple’s bedroom. She even turned down the offer of a candelabra from the Liberace estate because it would block the view — a key source of inspiration during the creative process.Ms. Flower describes herself as a homebody. But she would be that much happier at home if it had a dedicated recording studio and sufficient space to show off some of her mother’s artwork.“And,” she said, “there’s a third piano I want to buy. I asked my boyfriend, ‘What if we got rid of the dining table?’”For weekly email updates on residential real estate news, sign up here. Follow us on Twitter: @nytrealestate. More
