Indie rock is difficult to define until you hear this record’s amalgam of influences, assembled crazy-quilt style. Big, boisterous metal drumbeats share space with thumping, rhythmic bass. Vocals—often unison—are another rhythm instrument, and of course there are lots of crazy tempo changes, because what would indie rock be without that? Were the Eagle a little cooler, they’d almost certainly be a Chicago band, sharing a bill with some of this city’s other caustic, oddball rhythmmakers. But Ferocious Eagle is from Portland, Ore. Make what you will of that.
