the locomotion of vitality

from “the fun stuff” by james wood in this week’s new yorker, a personal history of keith moon:

There is no great difference between the live concert recordings and the studio songs: all of them are full of improvisation and structured anarchy, fluffs and misses; all of them seem to have the rushed gratitude of something achieved only once. From this exuberance emerges the second great principle of Moon’s drumming; namely, that one is always performing, not recording, and that making mistakes is simply part of the locomotion of vitality.
