(MUSIC) Ya heard? Tumultuous, orchestral post-rock is blowing up among the brightest, artiest kids, and New York's Tarantula A.D. are as artful and bright (in a dark way) as they come. Their new album, Book of Sand, bears surprisingly robust metallic flourishes amid its gorgeously baroque song structures. Come, and feel all cultured and shit.
