In November 2010 it was announced that Cluster had split up for the third time. In the official announcement, the split up was described as Moebius leaving the group. In the wake of this news, Roedelius announced that he was beginning a new project called Qluster, to follow on from Cluster and Kluster. The band is made up of Roedelius and accomplished electronic musician Onnen Bock with third member Armin Metz and released a trilogy consisting of ""Rufen"", ""Fragen"" and ""Antworten"" ("Calling", "Asking" and "Answering") in 2011.
