Florian Schneider and Ralf Hütter joined a quintet known as Organisation, which released one album, Tone Float in 1969, issued on RCA Records in the UK

sales were poor and RCA opted to drop the band shortly afterwards, at which point Hütter and Schneider-Esleben left the band to form Kraftwerk, with Organisation dissolving as a result.

Question: When did the band get together?
