“It’s music that you’re going to walk into a club and you’re not going to be saying, ‘Oh my God, we’ve got to get out of here,’ ” Seikaly said. “I play that music that you walk in and say: ‘O.K., I can put up with this. I may not like it, but it’s not offensive.’ ”

He laughed at the sound of that.

“It’s happy,” he said. “It keeps you there.”

Seikaly plays and creates what he called happy underground music. As a D.J., he takes pride in uncovering little-known tracks on the Web and avoiding dance-club anthems. And his original songs are electronically built atop steady, synthesized drums.

“When my mom tells me, ‘Son, your music sounds kind of all the same,’ I say, ‘That’s exactly what I thought about your classical music,’ ” Seikaly said.

Seikaly, who married and had a daughter with the model Elsa Benitez (the two divorced in 2006), has invested much of his time and money into the club scene in Miami Beach. He has had ownership stakes in a number of trendy hot spots, like Mynt, Bar None and Mokai. (He has no stake, however, in LIV.) On countless nights, he and close friends would retreat to his mansion’s “playroom” — a high-tech incarnation of the home disco he built as a child. (He has another such room, in a house he built in the 1990s in Beirut, where his parents live.)

The room feels like a mellow garage-size lounge, with dim lighting and a mirrored Buddha high on a shelf. The dark walls are lined with low couches. What looks like a bar holds CD players and a mixer, not drinks. The room is equipped with a hard-to-spot, club-level sound system.

Friends always wanted to bring more friends. Finally, in 2008, Seikaly agreed to D.J. for an expanded audience at Mokai, which he no longer owns.

“It turned out to be an amazing night,” Seikaly said.

Now he keeps a steady schedule at clubs around the world. He is scheduled to play at Lavo in Manhattan on Saturday; in Marrakesh, Morocco, later this month; and back in Miami Beach on New Year’s Eve.
