Alien Days

This dreamy, five-minute-long trip into psychedelia was premiered by MGMT on March 30, 2013 at the Festival Estereo Picnica show in Bogotá, Colombia. It was initially released on April 20, 2013 as a limited-edition cassette single for the Record Store Day campaign before being presented to the world as a free stream in promotion of their third eponymous album. Vocalist Andrew VanWyngarden told NME: "It incorporates some of the feelings that we experienced with the first two albums."

The child vocals were provided by Trevor, the son of Cool Little Music Shop's owner at Fredonia, New York where MGMT purchase some of their instruments.
