The original Ash Ra Tempel line-up got together to record Join Inn during breaks in the Tarot album recordings. The album's two lengthy tracks were completely improvised. The first, 'Freak 'n Roll' is basically self-explanatory(!) with Manuel Gottsching coming into his own with his talented, bluesy upbeat improvisations. 'Jenseits' (Beyond), on the other hand, is a showcase for Klaus Schulze's then new-found electronic sound painting skills. The lyrics on the 2nd track are read by Rosi Muller, new band member and then-girlfriend of Gottsching. She tells the story of the band's meeting with Timothy Leary and all the excitement that surrounded it.
