This indie-pop band is a pleasant surprise from Argentina, which in recent years has gained more notoriety for psychedelic cumbia and electronic folklore than gentle strumming and gauzy vocals. Like a cousin of Helado Negro or Petite Amie, this four-piece drifts breezily on “Despacio” from 2018 debut “Chango,” released by venerable Japanese label P-Vine Records. Spaceship bleeps and jazzy outré flute complement “Partenaire” on sophomore release “Una Caricia.” Their Freakout Weekender appearance occurs during the band’s first U.S. tour, four years after they first commanded the big stage at Lollapalooza Argentina. After warming up at SxSW and Treefort, Isla de Caras should be more than ready for their Seattle debut. GREGORY SCRUGGS
