With 'Join Inn' follows part 3 of the authorised 50th Anniversary 'A.R.T.' Re-Edition series, also in the meticulous Manuel Göttsching Re-Cut. The fourth Ash Ra Tempel studio album was released in 1973 on Ohr Musik, consists of two overlong tracks and is considered a highlight of the Krautrock movement. At the same time, it marks the end of the collaboration with Klaus Schulze, whose drums, paired with Hartmut Enke's bass, were a unique, irreplaceable dream team for Göttsching. This also includes two legendary last concerts in February 1973 in Paris and Cologne with this line-up.
