UKZ is an international progressive rock band, that was formed in 2007 by keyboardist/violinist Eddie Jobson, who had played in U.K. After a failed attempt to work on a proposed U.K. reunion album with John Wetton, in October 2007 Eddie Jobson announced a new band, UKZ, with Aaron Lippert, former vocalist for Expanding Man who had also worked with Jobson in the 1990s, Trey Gunn from King Crimson on Warr guitar,[1] guitarist Alex Machacek and drummer Marco Minnemann.

The project ended up becoming international, as each of the players were situated in different parts of the world and recorded their first EP "Radiation" without meeting in person.

[3] After releasing an instrumental MP3 track, entitled "Tu-95" (after the Soviet airplane), for download on 30 September 2008 and a videoclip of the song "Radiation",[4] UKZ played their debut concert in New York City's Town Hall in January 2009.

A UK reunion was officialized in 2011 and Jobson and Wetton toured together until 2016, under various line-ups that sometimes included UKZ members Machacek and Minnemann.

In November 2013, Lippert, Machacek and Minneman joined Jobson on stage for his brief Four Decades tour in Japan, to play three of the four songs contained in the "Radiation" EP.
