In the beginning was the groove, sorta, and it's from Australia

Music, Yes. The groove, not so much. Well, it's there, but James Brown funky, Ray Charles sanctified, it is not.

In the NYTimes:

“It’s a prosperity movement for the millennials, in which the polyester and middle-class associations of Oral Roberts have given way to ripped jeans and sophisticated rock music,” said R. Albert Mohler Jr., the president of the Southern Baptist Theological Seminary. “What has made Hillsong distinctive is a minimization of the actual content of the Gospel, and a far more diffuse presentation of spirituality.”

For young Christians in cities where Hillsong has churches, it has become a magnet, combining the production values of a rock concert, the energy of a nightclub and the community of a megachurch. Many of the worshipers say they are drawn by the music but have stayed because of the opportunity to be with other young Christians, and because they believe that the churches can help transform cities, both through prayer and through direct social services.

The cities are the new hinterlands:

“There’s no question there’s a real current of evangelical enamorment with cities,” Mr. Stetzer said. “Evangelicals have been a rural people historically, and the cities were the places where sin was. But cities are also where the people are.”

Hillsong chooses cities not only because of population density, but also because of their impact on culture.

“These are tough, hard, dry towns for contemporary churches,” said Brian Houston, the Sydney-based senior pastor of the Hillsong empire. “We want to be strategic, and really impact cities of influence, so that the influence can reach far beyond.”

Hillsong is all over YouTube: "The soundtrack to your faith."
