The Depeche Mode promo juggernaut continued Friday night with the band performing a tiny club gig at The Troubadour in Los Angeles to a crowd of about 400 KROQ contest winners and VIPs — and then proceeding to stun fans with the first-ever live performance of “But Not Tonight.”

Depeche Mode returned to “Jimmy Kimmel Live!” on Wednesday night for a follow-up to the band’s 2009 mini-concert, performing a short five-song set for a throng of fans, including its Delta Machine singles “Soothe My Soul” and “Heaven,” both of which were broadcast on the late-night show.

Depeche Mode will warm up for the opening of its Delta Machine world tour in Nice, France, early next month with a just-announced free concert in Los Angeles this Friday at The Troubadour, a 400-capacity club that radio station KROQ is calling “the smallest venue the band has played in L.A…. EVER!”

Depeche Mode today premiered a live in-the-studio performance video for Delta Machine track “Soft Touch/Raw Nerve,” a clip that appears to have been filmed at the same time as the second video released for the album’s lead single, “Heaven.” Check out the new performance footage of “Soft Touch/Raw Nerve.”

The Delta Machine promotional blitz hit U.K. television Saturday night as Depeche Mode appeared on “The Jonathan Ross Show” for a 10-minute interview segment with the seemingly pants-less host and a black-and-white performance of the album’s first single, “Heaven.”

With their new album ‘Delta Machine’ out this week, Depeche Mode today announced a new stop on its North American tour — Oct. 6 in Las Vegas — suggesting that the band will be filling in that conspicuous nine-date gap between its Los Angeles shows and the tour-closing gig in Phoenix.
