New York, NY – The world’s biggest DJ and critically-acclaimed producer, Tiësto, joins forces with Emily Haines of electro-influenced indie rock band Metric for his newest release “Knock You Out,” out on Ultra Records/[PIAS] September 29, 2009. This is Tiësto’s sixth track off his upcoming artist album Kaleidoscope, available 5th October , also on Ultra/[PIAS].

The new song, featuring the vocalist/keyboardist of Metric, follows up on the success of the album’s first five tracks which includes the album’s first single, “I Will Be Here” (ft.

Pricilla Ahn) were also introduced via a viral campaign that included premieres on sites such as Pitchfork, Stereogum, CosmoGIRL! and AOL’s Spinner. In celebration of this current release, Tiësto is inviting budding DJs and aspiring producers the chance to remix the euphoric tune in a new contest launching in conjunction with the industry leader in electronic music downloads, Beatport.

This is the first time ever that Tiësto has not only made his original music stems available to the public, but also given aspiring artists a chance for their own big break: up to three winning mixes of “Knock You Out” will be released commercially on Ultra Records and [PIAS].

Tiësto has also unveiled details of his new single ‘Escape Me’ starring indie-chanteuse C.C. Sheffield, better know as one half of LA rock outfit Le Rev.

It’s been quite a year for Tiësto, it started monumentally on New Year’s Eve with a performance to 250,000 people on a Rio de Janeiro beach and he hasn’t looked back since. This summer, Tiësto has performed to over 110,000 people at his record breaking residency at Ibizian Super-club Privilege, he’s played a succession of headline shows across Europe and festivals including Creamfields, and in July he became the first DJ to headline and sell out Victoria Park in London.

Furthermore, during this time Tiësto was putting the finishing touches to his fourth studio record Kaleidoscope, one of the biggest and most daring albums of the year. It features Kele Okereke from Bloc Party, Calvin Harris, Nelly Furtado, Tegan & Sara, Kianna from Tilly and The Wall, Emily Haines from Metric, and Jónsi from Icelandic post rock outfit Sigur Rós. It is without a doubt an album full of the most credible names and stars from all walks of the musical stratosphere.

The forthcoming single ’Escape Me’ featuring songstress C.C. Sheffield is a track that encapsulates Tiësto’s diversity perfectly. With C.C.’s raw rock vocal, a driving bassline that belies a pop punk influence coupled with Tiësto’s wondrously euphoric sound that brings this myriad of influences together, ‘Escape Me’ bears all the hallmarks of a classic single heading for the top of the charts

To coincide with the release of ‘Escape Me’ 4 very special remixes are in the works from Italian Italo giant Alex Gaudino, electro duo LA Riots, Avicii and a progressive cut from Marcel Woods.

Furthermore, the Kaleidoscope tour kick started into action this week with three back to back shows at the Hammerstein Ballroom in New York where patrons wdere treated to a no expense spared, iridescent live show that will transform into a fantastical celebrations of dance music itself.
