Stockholm Strings, a quartet from Sweden who’ve played with Brian Wilson or anyone else seeking an ensemble beyond capable of accompanying fine tunes, just teamed up with hometown folk duo First Aid Kit for a live session. This song, “Cedar Lane,” is off their Mike Mogis-produced Stay Gold, the Söderberg sisters’ follow-up to The Lion’s Roar. The studio album is impressive, but this take pulls at the viola, violin, cello, and heartstrings even better. It’s inspired, filmed beautifully, and lovely — they should make a whole record together. Check it out above.
