Boxed closed in 2001 and was superseded by Global Underground Ltd. Since its first release in 1996, the series was well received and became a hallmark in the progressive house world. The dance music style featured is mostly progressive house, but there is some house, trance house, hard house, techno and breakbeat included in the releases. The first five installments were live recorded from respective clubs, while the rest are mixed and recorded in a studio.
