On "It Started with a Mixx," Los Campesinos! explore the neuroses of an indie rock world where the mixtape is the highest form of courting. The tone is, at first glance, snarky and ironic, but there is an affectionate, somber edge to the song, a combination that aptly sums up the Welsh septet on its 2007 EP, STICKING FINGERS INTO SOCKETS. In the vein of a Camera Obscura that's always set on upbeat, the outfit pairs literary lyrics with more simple observations in a manner almost Swiftian, particularly on the opening volley, "We Throw Parties, You Throw Knives."
