II is the second studio album from the band Unknown Mortal Orchestra, released in February 2013.

[7] AllMusic gave the album four out of five stars, saying "from the opening moments of the trippy, lo-fi intro 'From the Sun' all the way to the funky-as-a-Hendrix-ballad closer 'Secret Xtians,' II takes risks and achieves greatness.

"[8] NME gave the album eight out of ten, saying "raw melody made Unknown Mortal Orchestra exciting two years ago; now they’ve matched it with attention to detail.

"[1] The Observer gave the album three out of five stars, described "Swim and Sleep (Like a Shark)" as "conjoin[ing] sleep, prettiness and unease", and the album as having "longueurs where Nielson can get a little vague and inward-directed.

"[12] II won Best Alternative Album in the 2013 New Zealand Music Awards.
