Carlos Pineda, Eric Livingston, and T.J. Swan are Entropy Density, a San Francisco band that's carefully muddled together elements of shrieking barber shop anti-harmony, dreamy California post-rock alla Tristeza, and unapologetic, blissful noise, and that's just in three songs. These tracks appear on a CD-R entitled (((∞)))), but look out for a vinyl EP this summer.
