Brothers Roger Eno and Brian Eno released Mixing Colours, their first ever full-length collaborative duo album, back in March. There were colors they left off the album, though, and those will make up a new seven-track EP, Luminous, that will be released on September 25 via Deutsche Grammophon. They're all in the same gentle piano style as the album and you can check out "Manganese" via its music video below.

Luminous will also be part of a new expanded edition of Mixing Colors which will also be out 7/17.

You may also remember that Brian and Roger were accepting video submissions to be used as official visuals for the album. "We were overwhelmed - both figuratively and actually - by the responses to our call for films," say the brothers. "The quality was so high! And the number so large! It is really heartening to know that people are looking at the world around them in a curious and creative way." They've narrowed submissions down to 200, each of them assigned to one of the Mixing Colors tracks. If you submitted a video you're allowed to vote, and you can view the videos here.
