Disambiguation; There are 8 Groups with the same name. 1) A death metal band from Poland started in 2004; 2) A rave/happy hardcore group from The Netherlands, popular in the Mid-Nineties. Critical Mass was formed in 1994 by Ed Bout and Dave Hasselaar. ID&T records (the centre of hardcore at that time) wanted a live act. At the beginning both producers where the act by themselves but not much later they integrated the singer Ludmilla Odijk and rapper Danny Haenraets alias MC Energy. At the end of 1995 they got a hit with "Dancin' Together". In 1996 3 big hits followed: "Burnin' Love", "Believe In The Future" and "Happy Generation". In 1997 another single followed called "Together In Dreams". In 1999 the group tried again with a trance single called "In Your Eyes", it became a clubhit. "In Your Eyes" and "Together in Dreams" (both being eurotrance tracks, and not happy hardcore) were picked up by Byte Records. But even Byte failed to make Critical Mass succeed; 3) A contemporary catholic rock band started in 1997 by David Wang. Their first demo recording, Faith Looks Up, won Best International Group and Best Modern Rock/Alternative Album honors from the United Catholic Music and Video Association.
