The group consists of 2 rappers/songwriters Mike Griesheimer & Thomas Detert, singer Helen Smith and producers Alexander Stiepel & Andreas Hoetter (A-Team).
Their first single to be released was "Save Me" in 1994. Then followed in 1995 the hits "Let The Rhythm Take Control", "I Say What I Want", "Inside And Outside" and "Tell Me".
That year their album "Visions" was also released.
In the middle of 1996 the track "Rhythm And Drums" was released. Anticipating Eurodance's decrease of popularity, they wanted to introduce a new style, but the single flopped all over the world. Then they decided to give up Activate and to establish the 666 project. The debut-single from 666 "Alarma" is a remake of the Activate-song with the same name.
