British electronic act Underworld will take part in the 2007 Electronic Beats Festivals, the flagship live-music event for wireless carrier T-Mobile International.

This year's fest tour kicked off early June in Budapest, Hungary. It continues in Halle E in Vienna, Austria's Museum Quarter on Sept. 29; at Prague, Czech Republic's National Gallery on Oct. 27; and at the Expo in Bratislava, Slovakia, on Oct. 31.

Underworld will headline in Prague and Bratislava, as part of a world tour that will see the duo play in Portugal, Spain, Germany, the Netherlands and Belgium.

Underworld's tour will support the release of "Oblivion with Bells," Underworld's first studio album since 2002's "A Hundred Days Off" (V2).

In the United States, where Underworld is signed to Chrysalis, the act plays at the Hollywood Bowl (Los Angeles) on Sept. 9, at Red Rock in Denver on Sept. 11, and at Central Park in New York on Sept. 14.

Meanwhile, Danish dance act Trentemoller will headline the Vienna Electronic Beats event, which has a bill featuring the U.K.'s Goldie (featuring MC Lowqui), Havana-originated Cuban Brothers, and Germany's DJ Koze.

T-Mobile will unveil other acts in the Prague and Bratislava line-up in the coming weeks.

An extra Electronic Beats Festival is expected to be lined-up later this year, details for which remain unconfirmed.

This is the third year for T-Mobile's Electronic Beats Festivals, which typically rolls out four to five events catering for European markets in which it operates.
