This is the record label of Dutch party organisation Q-Dance. They focus on the harder styles of dance music, such as hardstyle, hardcore, techno and hard trance.
The regular releases (so excluding the compilations and gifts) until 2005 have two catalog numbers.
One for Q-Dance only and one in the typical ID&T style. These releases came in colored covers, each cover got his own color and style like orange for hardstyle, green for techno, blue for hardtrance. Release number 9 got skipped for no reason.
The new releases have a Q-dance number and are all anthems of their major events.
