Live, singer Jae Kristoff often disguises himself by wearing a Mexican wrestling mask, but here he shows a different side, full of confident urgency and driven to greater heights by the long, flowing melodies strung throughout the record. As with anything experimental, Natural Selection has sour moments -- "Mail Bomb" kills the album's momentum, sounding like Green Jelly fumbling through a techno song. You'll forgive and forget, though, if only to say thanks for "Best in Show," the best 58 seconds in Cleveland music this year.
