Cover art for D.I.A.L.O. lyrics by John Vanderslice

" Romanian Names still offers plenty of catchy hooks and sing-along harmonies, but Vanderslice says he was less concerned with obvious narratives and more concerned with melody and craft. In "D.I.A.L.O.," the album's most infectious track, Vanderslice picked the cryptic acronym just for the way the letters sounded together; otherwise, they mean nothing at all. Ironically, a Google search for "D.I.A.L.O." turns up the Defense Intelligence Agency Liaison Office."

A little disappointed honestly.
