Uruguayan indie singer-songwriter Juan Wauters has a new album called Wandering Rebel on the way. Today he’s sharing its latest single, a duet with Frankie Cosmos’ Greta Kline called “Modus Operandi.” The song is a string-laden ’70s pop throwback, and it has a video by Fatos Marishta featuring Wauters and Kline wandering Montevideo and NYC streets attempting to communicate with flip phones.
