It may come as little surprise that Ms. Richards, 21, credits her euphonious childhood home with her ability to feel out the mood of a crowd, spinning in a way that both responds to and enlivens the mood. “I get most of the music from my dad. I grew up around it, so I love playing it,” she said, nodding and smiling.

Last night, after starting out with some welcoming reggae, she moved into an oldies set that, in its arrangement, felt surprisingly newfangled. Ms. Richards then finished up with a chain of cool-and-catchy indie tunes, which comprised a hefty sampling from her favorite bands du jour—“I’m obsessed with Arcade Fire, the Klaxons, LCD Soundsystem,” she said. “I think there are a lot of great bands coming out, and I totally support all of them.” She added that she has most recently fallen for a band out of Denton, Tex., called Midlake, whose song Young Bride she particularly loves.

Ms. Richards also paints. And she has an interesting method that works her love for music onto the canvas. “All my artwork is all based on a certain song I listen to. I paint to one song only. I repeat it over and over again. I just go at it. It doesn’t necessarily have to be about the painting or like what I’m painting, but just that feeling, you know? You get that inside.”

She and fellow DJ Nick Cohen have recently split, Ms. Richards said, but they remain good friends. “[Nick and his business partner, Seth Campbell] are doing really well, and they are now starting the women’s shoe,” she offered, referring to Mr. Cohen’s line of flashy kicks that the Transom wrote about last June.

We asked her if she wants to make a full-time career out of either painting or DJing at clubs and parties. “I’m still young and I’m trying to figure that out—if I love my painting more than the music or the music more than the painting. But I think both go really well together,” Ms. Richards said.

“Keep your eyes open,” she added, “because I’m going to come out with some really great stuff.”

First up, we negledted to mention Alexandra Richards, daughter of Rolling Stones guitarist Keith Richards and boyfriend of D.J. and Sneaker-preneur Nick Cohen, who spent the evening rocking out at Bella’s, the clubby lounge beneath Bar Martignetti dressed in a thong bodysuit over leopard-print tights and a black patent-leather belt

“The highlight of my evening, tonight, was being with my girlfriend," she told us. "We got a little wasted in my bedroom and dressed up in a bunch of outfits and decided to come out as 80's metalists, rockers, groupies!”

At the time she was kneeling on a red-leather banquette, nearly smothering said friend, a similarly-kitted-out young woman who called herself Elena Mercedes.

Exactly what kind of groupies they were didn’t matter much to Ms. Richards, whose dirty blonde hair was tussled around heavy black eyeliner.

“Any metalist groupie, yeah—Kiss, Metallica—we just wanted to go hardcore. My favorite memory of Halloween is right now. My best friend E.B. is performing with Blood Street right now,” she said, looking back at the band while starting to dance in character.

Meanwhile at Cipriani 42nd Street, Roberto and Eva Cavalli joined up with Giuseppe Cipriani to host a big Halloween bash, and Tinsley Mortimer arrived sans hubby Topper. No big surprise there. Ms. Mortimer told the Daily Transom that she decided to dress as an angel because her white Cavalli dress “had the little feathers.”

A few minutes after the ubiquitous socialite finished admitting to a New York mag reporter, dressed as a member of Daft Punk, that she feels a little poor after having recently purchased an apartment, Russell Simmons arrived with his leggy lady Porschla Coleman.

Sporting a Run-D.M.C. costume (black leather jacket, thick gold chain and feathered fedora), Mr. Simmons told us how he is able to maintain such a seemingly great relationship with his ex-wife, Kimora Lee Simmons, from whom he filed for divorce in March of 2006.

“She’s one of my best friends—parents, partners. We have lots of businesses, including raising children,” he explained, before making a b-line for the party, Ms. Porschla in tow.

Other guests at the bash included Andrew Saffir and Daniel Benedict, Bethenny Frankel, Britanny Gastineau, Beverly Johnson, A.N.T.M.’s Caridee English, Jamie McCarthy, Candi McCarthy and Billy Herndon, Ice T and Coco, Chudney Ross, Eva Amurri, Eve, Jason Colodne, Bethany Frankel with an anonymous Naked Cowboy, Jeff Gordon, Kelly Killoren Bensimon, Leighton Meester, Petra Nemcova, Vanessa Trump and Donald Trump, Jr.

Burp!

Called U.E.S. (after the Manhattan neighborhood where Mr. Cohen grew up) White Perforated Leather (self-explanatory) SENI (a hybrid of Mr. Cohen’s first name with that of his business partner, Seth Campbell, also 23), the ritzy kicks will retail for $500 per pair. In place of shoelaces, they feature chunky 18-karat gold-plated chains designed by jeweler Gabriel Urist and made, Mr. Cohen said, “at one of the best factories in China.”

He was speaking to The Transom by phone while he waited at the D.M.V. like a mere mortal. “We wanted to go high-end with it,” Mr. Cohen said of his collaboration with Mr. Campbell. “We have both always loved footwear and everything like that.” But the two were sick of the retro-sneaker trend. “There are a million different colors out there, and it’s tired and bored!” complained Mr. Cohen, who has invited Vogue editor Anna Wintour to a party introducing the sneakers, to be held on Wednesday, June 13, at AS on the Lower East Side.

Jeff Goldstein, owner of Blue and Cream, a boutique in the Hamptons—where Mr. Cohen spins at the clubs Dune and Stereo by the Shore during the summer months—is a fan of the new look, though he admitted it’s been hard to find customers at the three-figure price point. “They’re something that’s great to wear to a cocktail party when you want to look crisp,” he said, adding, “They tend to get fucked up in a club.”

And how is it going with Mr. Cohen and Ms. Richards, 20? “It’s beautiful,” Mr. Cohen said. “We’ve been together for about three years and she’s a great girl and life is good.” Oh, yay.
