Having recently released their third album, Unknown Mortal Orchestra are returning to Barcelona for the second time this year. Primavera Sound played host to the group in May and the performance was unforgettable. Multi-love (2015), their newest album, is full of emotion and energy, sharing some fairly intimate information about the love life of singer Ruban Nielson's love life. Their sound is a mega-mix of R&B sounds, with traces of disco and psychedelic guitar riffs. All you could want in a band really.
