In April 2008 the group played three shows in US cities Minneapolis, Milwaukee, and Denver, and were a coheadliner at the Coachella Valley Music and Arts Festival. This was their second appearance at the festival since 2004. Further shows were performed in Ireland, Poland, Ukraine, Australia, New Zealand, Hong Kong and Singapore later that year. The touring quartet consisted of Ralf Hütter, Henning Schmitz, Fritz Hilpert, and video technician Stefan Pfaffe, who became an official member in 2008. Original member Florian Schneider was absent from the lineup. Hütter stated that he was working on other projects. On 21 November, Kraftwerk officially confirmed Florian Schneider's departure from the band; "The Independent" commented: "There is something brilliantly Kraftwerkian about the news that Florian Schneider, a founder member of the German electronic pioneers, is leaving the band to pursue a solo career. Many successful bands break up after just a few years. It has apparently taken Schneider and his musical partner, Ralf Hütter, four decades to discover musical differences." Kraftwerk's headline set at Global Gathering in Melbourne, Australia, on 22 November was cancelled moments before it was scheduled to begin, due to a Fritz Hilpert heart problem.
