One late October evening at the night spot Cielo, there was a scene rare for Manhattan dance clubs. As the D.J.’s the Martinez Brothers were nodding their baseball-cap-adorned heads to their energetic house and techno set, their father, Steve Martinez, stood guard beside their booth. The siblings - Christian, 17, and Stevie Jr., 20 - headline hedonistic superclubs. But by morning Dad will make sure Christian is in class at Monroe-Woodbury High School in Monroe, New York, where the family lives. The Martinez Brothers, often referred to as TMB, are bridging genres, and generations, with their youthful-yet-knowing D.J. sets, mixing American house music (a soulful electronic successor to disco) with the ultramodern techno preferred by European clubbers.

The Martinez Brothers have established themselves in Europe, headlining parties in places like Berlin and Ibiza, Spain; they were recently part of a cover of Mixmag, a British dance-music journal, that was devoted to rising stars, and their profile in the United States is set to rise as well. The duo recently released their second single,“Debbie Downer.”

A few weeks after the Cielo gig Stevie Jr. and Christian gave an interview in the living room of the house they share with their sister and parents. Getting into dance music“was natural for us,”Stevie said. His father, nearby, listened closely. In the early ‘80s Mr.Martinez, 46, was a New York club kid himself.

In early 2005, relying on his club connections, Mr.Martinez produced a trio of downtown loft parties to introduce Stevie and Christian to the old guard of New York’s dance-music scene.

Meanwhile, Christian was using MySpace to befriend his favorite D.J.’s and producers, including Dennis Ferrer, the New York dance-music veteran. Christian sent him Web links to TMB’s sets, and Mr.Ferrer offered him and his brother the 4 a.m. slot (clubbing prime time) at the prestigious New York club Shelter.

“I had no idea that they were great,”Mr.Ferrer said. But five songs into TMB’s set, Christian said, people abandoned a set by a more popular D.J. upstairs and rushed into their room.

Mr.Ferrer said that without“the injection of youth, we’ll be playing to the same old cats we’ve always played to. Not that there’s anything wrong with it, but if your audience doesn’t grow, it stagnates.”The“hiphop kids”are“thirsty,”he added.“They want something new. They see ‘we’ve got somebody our age we can look up to.’”
