October 2007, Jobson announced a new band, UKZ, with Lippert and former King Crimson bassist/guitarist Trey Gunn among others, which released an EP called "Radiation" in March 2009. In late 2009, Jobson and Wetton both talked about a possible reunion of U.K. A reunion tour in February/March 2010 with Jobson, Wetton, Marco Minnemann on drums (from UKZ) and Greg Howe (Victor Wooten, Vitalij Kuprij, Michael Jackson) on guitar was described to promoters, but would not happen until 2011. Wetton and Jobson performed three concerts in Poland in November 2009 as part of Jobson's Ultimate Zero (U-Z) project. The line-up also featured Minnemann, Howe, and Tony Levin (stick). They performed music from UK and King Crimson. A CD compiled from various U-Z performances from 2009, entitled Ultimate Zero Tour - Live, including multiple tracks from the Polish shows, was then released. It was announced on 11 February 2011, and later confirmed by John Wetton on his website, that U.K. had reformed to play two shows in Japan on 15 and 16 April 2011. The line-up was Jobson and Wetton, with Minnemann and Alex Machacek performing drums and guitar respectively. US dates, including a show in San Francisco, were also announced and performed in April 2011. A DVD called "Reunion: Live in Tokyo" was culled from these shows and officially released in 2013. Former drummer Bozzio then rejoined for an American tour in 2012. The line-up for the subsequent European tour included additional musicians Gary Husband (drums) and a returning Alex Machacek on guitar. In 2013, U.K. did an "Azure Seas" tour with Machacek once again taking on guitar duties, and an East Coast tour with Virgil Donati performing drumming duties in place of Bozzio, who had once again departed the band. On 8 November of the same year, the band did also a special concert performance of their two studio albums in Kawasaki, in Japan. The drummer for that special concert was Marco Minnemann. U.K. appeared in the 2014 edition of Cruise to the Edge progressive rock festival. The line-up once again included both Machacek and Donati. In 2015 the band announced their final world tour, with the band being joined by Donati and Machacek. Donati was then replaced by Dream Theater drummer Mike Mangini for the final dates in the USA and Japan. Musical style Throughout their brief existence, U.K.'s music was characterised by skilled musicianship, jazzy harmonies, close harmony
