RAG arose from two earlier (and still active) hip hop collectives in the Ruhr Area: Filo Joes (with the two MCs Pahel and Galla) and Raid (MC Aphroe and DJ Mr. Wiz).
Raid and Filo Joes encountered each other at jams and other events – they discovered they were linked by a similar mentality, and decided to make music together under the name "Ruhrpott AG".
One of their earliest recordings (although not actually released until it appeared on their second album, P.O.T.T.E.N.T.I.A.L) was the original version of "Tief im Westen": a stream of emotions, associations, similes and metaphors concerning the band's native region, the "Ruhrpott", painting a multi-layered and often contradictory but nevertheless affectionate picture.
RAG's lyrics and beats, particularly on Unter Tage, conveyed a fairly heavy and melancholic mood, with the band members expressing their feelings about their lives in the Ruhr Area.
The second album, P.O.T.T.E.N.T.I.A.L, expanded their range from the early heavy, dreamlike style towards a harder-edged, more concrete lyrical approach in which the storytelling was not always shrouded in indirect imagery.
