Back in Norway 2005, the 2 DJs Thomas and Fredrik met for the first time and started a collaboration later known to become the project "Adrenaline Dept." who firmly kept top positions with both vinyl and digital singles and compilation-releases on labels like Ministry of Sound, Tidy, Masif, Tunnel Trance Force, Riot, Impact, Deprivation and Oblivion in the hardtrance charts between 2006 and 2010.

In 2010 they left the hardtrance scene to pursue other ventures within music, but in 2018 they both felt something was missing in life and decided it was time to return. Lots of studio-time has been put in to form the new sound and they have had a tight release-schedule with new tracks nearly every month from summer 2018 going forth. In August 2019 the remix of the iconic track "Phatt Bass" by the Warp Brothers was released and gained support from names like Giuseppe Ottaviani, Scot Project, Tempo Giusto, Johan Gielen and many more and reached #15 on Beatport Top100 Trance.
