From his earliest demos to his current position as a key figure in the global techno scene Perc (aka Ali Wells) has taken the established forms of the music he loves and twisted them into something new and fresh. Key to Perc's recent success was the release of 'Up' on Kompakt. With its unmistakable relentless rising tone 'Up' lodged itself in record boxes including those of Richie Hawtin, Luciano, Chris Liebing, Misc, Slam, John Digweed, Green Velvet and Steve Lawler. Perc's 2nd Kompakt release 'Headphone Heart' showed his versatility, mixing industrial-strength percussion with a haunting flute melody, a combination that should never work, but Ali pulled it off.

To cement his techno credentials Ali's 'Sticklebrick' EP on Adam Beyer's Drumcode label made him the first non-Swedish artist to release on the label in 7 years and showed that he could produce to a standard equal to the world's best. Ali also has built a successful relationship with Chris Liebing's CLR imprint. Releasing his 'Serious Moonlight EP' in 2008 and following it up with the Berghain approved 'Submit EP' in May 2009 Ali's CLR releases have covered a wide range of territory. 2009 saw Ali make his debut on Josh Wink's internationally renowned Ovum label. In 2010 and 2011 this was followed with releases on labels such as Electric Deluxe, Sleaze Records and Stroboscopic Artefacts.

On top of all this is Ali's own Perc Trax label, with over 50 vinyl and digital releases featuring a who's who of modern house and techno including James Holden, Nathan Fake, Misc., Peter Van Hoesen, Norman Nodge, Gary Beck, Kyle Geiger, Avus, Mihalis Safras, Matt Tolfrey, Ripperton, Xpansul, Donor & Truss, The Delta and Drum ‘n’ Bass legend Ed Rush, demonstrating the label's eclectic nature perfectly. In 2011 his first album ‘Wicker & Steel’ also appeared on Perc Trax.

Perc is also in-demand remixer having been commissioned to remix a host of world-class names including Trentemoller, James Holden, DJ Hell, Misc, Phil Kieran, DJ Yellow, Blood & Tears, Jeff Bennett, Gary Beck, Misstress Barbara, Kyle Geiger, Max Cooper and many more. His most notorious re-rubs include his driving take on Holden's own 'First Light' and his reworking of DJ Hell's 'Buttersaure' that had the cream of Europe's techno scene salivating. As Perc's profile grows his booking schedule has become busier and Ali's touring has covered all of Europe plus tours of USA, Canada, Mexico, South Africa and 3 tours of Japan.
