Those with eidetic memories may remember this post I made almost exactly 5 years ago:
A couple of nights ago, in a bout of insomnia, I ended up channel-surfing at 02:30. My attention was captured by a music video on MTV2. It was long - over 5 minutes, maybe even 10 - and featured starbursts, video-game spaceships and small octopuses (it was also a bit psychedelic, if you hadn't guessed already).
[...] Does anybody have the first clue what track/artist I'm talking about?
Today, I answered my own question, totally accidentally, by buying the album.
I'm somewhat embarrassed to notice I left out one further detail which is still fresh in my mind: I reckoned the lyrics said something about "a thousand ambassadors", which might have helped people a bit.
While (as it turns out) I underestimated the diplomatic quotient by three orders of magnitude I was pretty close considering I was befuddled by lack of sleep:
12 minutes long. starbursts. blurry CGI spaceships. octopoids.
Also, mellow electronic burbling, vocal harmonies (with lyrics that make no sense whatsoever) and a really good'n'heavy guitar riff at about the 8'30" mark.
 fx: counts raised hands. doesn't take very long.
 certainly helped me when I played said album for the first time and went, "hang on a minute, is that what I think it is?"
 the actual lyric is "a million bright ambassadors".
