The "Three Orchestras and Stars" concert on June 6 will include performances by the Bavarian State Orchestra, led by Zubin Mehta; the Munich Philharmonic, led by Christian Thielemann; and the Bavarian Radio Symphony Orchestra, led by Mariss Jansons.

The concerts are apparently intended as successors to the spectacularly successful Three Tenors concerts, which featured Domingo, Luciano Pavarotti, and Jos_ Carreras and opened a series of World Cup finals starting in 1990.

The 2006 World Cup finals start on June 9 and will be held throughout Germany. The championship match takes place in Berlin on July 9.

Tickets for the June 6 concert are 25-124 euros. For more information (in German) visit www.3orchester.de.
