On Dirty Projectors sixth album, Swing Lo Magellan, songwriter and leader David Longstreth shows he really doesn't know how to do the same thing twice. Where prior Dirty Projectors albums investigated 20th-century orchestration, west African guitar music and complex contrapuntal techniques in human voices, Swing Lo Magellan is a leap forward again. It's an album of songs, an album of songwriting. Swing Lo Magellan has both the handmade intimacy of a love letter and the widescreen grandeur of a blockbuster, and if that sounds like a paradox - it's because it was until now.
