"Hardcore" albums always contained big dance hits first, and then less well-known, underground tracks at the end, making the series an attractive purchase for mainstream dance fans as well as underground followers of the genre.After a series of one-off Dance compilations including "Cold Sweat" and "Trance Dance", Dino launched a new Dance series called "Energy Rush" in late 1992 which out-lasted the "Hardcore" series by many years.
