King DJ is aka 4T4. He makes the music. He's a very well known dj with tons of experience. He's also been producing many different styles of music for quite some time, and with great succes. The hiphopgroup 't Hof Van Commerce not in the least. He's currently doing lots of stuff in the cosmic disco scene (on labels like Bearfunk, Nang records,...). Check out the King DJ myspace page for more details on the future and present, and the 4T4 page for the past. U7's music is released on his own new record company Regalia.

Tom Derie is the singer. He used to sing in the legendary Belgian band Soapstone, now has a rockband called The High Standards. He looks like Leo DiCaprio on steroids, sounds like Bobby Womack on crack and smells like beluga with ketchup. His favorite woman is your girlfriend and he's president of the East Ghent Claude François fanclub. His chocolate mousse is the best dessert this world has to offer.

Ultrasonic 7 was founded in 2002 as Ultrasonic without the 7, which was added later to avoid confusion with other artists. They have scored a couple of hits in 2003 and 4 on a national level, mainly the cult classic Lips They Move. The group used to include soul singer Nia Saw and Uwe Teichert, and has a very strong live reputation. They've played in many different formations, but most notably it usually (and still) involves trumpet player Yves Fernandez, playboy extraordinaire, and Björn Denys, percussionist to the gods on Mount Olympia. They have an album called "Ultrasonic 7 Makes You Sweat", which was released through PIAS in 2004. Then the whole thing went somewhere, only to come back more than 5 years later in downsized but updated version. Hopla. And now they're back. With a vengeance... They come to get down and get down you will.
