It took a  lengthier-than-expected  internal debate to convince myself that I shouldn’t name this week’s column for Isis’s 2002 album Oceanic, if only because I’d wager that most of you would look at me (or this column) with some bafflement. “Yes, Toby, we get it–but what do whaling disasters have to do with experimental metal bands?” So instead: metaphor, unreliable narrators, Aphex Twin, and cannibalism.
