Karen O & Danger Mouse released their collaborative Lux Prima album last year, and have now released a cover of Lou Reed classic "Perfect Day" as an Amazon Music exclusive. Unlike the sweeping original, they take an understated approach, with gently strummed guitar, light synthy strings and Karen's fragile vocal delivery. Listen to that below.

Meanwhile, Karen O and Danger Mouse are up for Best Rock Performance at this weekend's Grammy Awards for “Woman” off the Lux Prima album. Watch their Colbert performance of that song below as well.
