Unknown Mortal Orchestra: SB-09

Each year, Unknown Mortal Orchestra releases an instrumental song over the holiday period and the latest, “SB-09,” provides listeners with 19 minutes of laidback, meandering, genre-blending bliss. With Ruban Nielson on guitar and his brother Kody on percussion, the song comprises elements of post-punk, surf-rock, reggae and more with tropical guitar, barking dogs, voices and other effects. On Twitter, Nielson said the shapeshifting track is “dedicated to chance.”
