I builds on the break-beat, junk-shop charm the multi-instrumentalist and songwriter Ruban Nielson came to be renowned for following Unknown Mortal Orchestra's self-titled 2011 debut, and signals the solidification of the band's position as an endlessly intriguing, brave psychedelic band. UMO is unafraid to dig deeper than the rest to lock into their intoxicating, opiate groove and bring rock'n'roll's exaggerated myths to life. Written during a punishing, debauched touring schedule during which Nielson feared for both his sanity and health, II illustrates the emotional turmoil of life on the road, painting surrealist, cartoonish portraits of loneliness, love and despair.
