Glockenspiel has become one of the calling cards of Sufjan Stevens’ epic opuses. The biggest and most complex piece from his first hugely impactful album, opens on the instrument alone. Oh Detroit, Life Up Your Weary Head (Rebuild! Restore! Reconsider!) then proceeds to through every other instrument in Stevens’ stable at the tune to create his signature, galloping cacophony. The glockenspiel theme is repeated by heavy, blaring brass, but the welcoming tones of the opening few seconds are never out of mind for the rest of the song.
