Every once in a while, I get a hankering for music that makes my head feel like an eggbeater got inside and is twirling away, one of the old fashioned hand-powered kinds. Symmetry in the repetitive motion, twin yellow whirlpools, all that. So coming across Nico Muhly’s “Mothertongue” album when looking for composer inspiration at work was pretty exciting. I’ve only listened to it with headphones, which really makes it feel like it’s invading every brain wrinkle, so if you’re in the mood to get mind-scrambled that’s the method I’d recommend. It’s also fun to imagine the process of recording the album.
