By 2007's Whatshewants EP on Marine Parade, his sound had begun to incorporate crunchy, cut-up guitar riffs and occasional vocals. Several singles and EPs followed on Marine Parade, continuing in a more song-based direction. 2011's "It Starts" was an uptempo pop/rock tune similar to the French band Phoenix, whose single "Lisztomania" Metric had remixed. Metric also remixed songs by artists including Gorillaz, N*E*R*D, Ellie Goulding, and Bloc Party; 2011's Open Your Eyes (Positiva/Virgin) collected many of these, as well as collaborations with Steve Angello, Stone Roses' Ian Brown, and Charli XCX, which were released as singles.
In 2012, Metric self-released a three-song EP titled Ammunition. He then signed to Skrillex's OWSLA imprint, who issued Ammunition, Pt. 2 later that year, followed by Pt. 3 in 2013. Metric's most anthemic single yet, Jacques Lu Cont collaboration "Safe with You," appeared on Ministry of Sound in 2013. A less vocal-centered EP called Hope appeared on OWSLA in 2014, and another poppy single, "Heart Weighs a Ton," was released by Warner. In 2015, OWSLA released Ammunition, Pt. 4, which included collaborations with the Knocks and the New Sins. ~ Paul Simpson, Rovi
