An experimental composer and occasional film scorer as adept with layered sound-collages as with proper ensemble arrangements, Baltimore’s Dan Deacon has piled all facets of his musical persona together here. “Crash Jam” begins with a squashed bass note buzzing in and out of sequence with crinkling squeals. Buried underneath, a more traditional rock song undulates. It soon devolves into a storm of clattering percussion before an abrupt transition into “USA I: Is a Monster.” That track, too, quickens into a cavalcade of static-electricity feedback and kitchen-sink textures. Percussion dominates over circuit-board effects before the strings reemerge. The rest follows a similar pattern, building from an abstract mess of painterly sounds, splashed rythmically against the wall. Focusing on one idea is like watching the road at night through a foggy windshield as headlights glimmer off a hard rain — you can only make out the way ahead if you pay careful attention.
