As they're slightly heavier than water, sharks need to keep moving unless they want to sink. So if sharks wore personal stereos, you'd expect them to listen to something energetic and vicious -- Atari Teenage Riot, probably. Or perhaps they'd listen to Ricky Martin in order to heighten their desire to kill and maim everything in sight.

If any actual sharks listened to Sharks Keep Moving, I think a big group of them would get together, have coffee and question the nature of their existence as carnivores. It's a contemplative disc, heavy with intricate time signatures and low-key indie rock ambience despite the bandmembers' hardcore credentials. It's sedate and sometimes bleary, but also intensely deliberate -- these aren't unstructured, endlessly-circling jam sessions. While the disc's instrumentals are strong (particularly the jam-packed final minute of the cleverly-titled "Third Instrumental"), it's the motion-centric lyrics of the remaining four songs that truly cement the disc's feeling of restless sentimentality. While "Join Up" strides deliberately forward, putting its past behind it, "Open Bay's" indelible fishing-with-dad imagery reminds us of the world of motion that exists even when time seems to stand still. Will Sharks Keep Moving move you? If you're all about aggressive rhythms and constant predatory motion, it might slip quietly past you...but if you're a slow, deliberate, Tortoise-type listener, you'll be content observing its gradual progress.
