 Conrad Schnitzler left Kluster in mid 1971, briefly to continue work with the band Eruption and then to pursue a solo career.Schnitzler claims that Eruption toured under the name 'Kluster' at the time, and under that pretext re-released in 2009 under the Kluster name two albums originally labelled as being by Eruption.After the original lineup of Kluster split, Roedelius and Moebius continued with an anglicized version of the name, Cluster, initially together with Conny Plank, and from 1972 onwards as a duo.
