We know the promise: get out while we're young. The rings say nobody leaves. Jade (E) holds the key in 14 of 18 sections, and the dynamic range is 3 decibels, one sustained roar. The voice is present just 14% of the running time. The loudest moment lands at 88% of the way through, and the words run out before the voice does. The most exhilarating escape song ever recorded is a circle.
