With contributions to the soundtracks for Her, Where the Wild Things Are and a leaked collection of home-recordings, it's clear that Karen O is no stranger to going it alone. That said, the Yeah Yeah Yeahs frontwoman's first official solo album Crush Songs doesn't come out until next week and aside from the bite-sized indie pop masterwork "Rapt" we haven't heard much from that record, aside from the news that it catalogs a period of O's life that was dominated by an "ever continuing love crusade." Today, she's mercifully issued another a dusty and downcast bedroom recording called "Day Go By." It's built around little more than O's voice and a messily strummed acoustic guitar, but it manages to use its two minutes to craft a lovely little tale of lovesickness. Listen below and pre-order Crush Songs, which is out September 9 on Julian Casablancas' Cult Records.
