There's an even better version of 'Puppies' at the end of their 'Everything Everything' DVD (whilst the credits are rolling) - they strip it back to the bare minimum - no beats, no vocals - just those beautiful deep synths. I honestly think it's the best ambient track ever made (a big call, I know!). Unfortunately, it's not on youtube (it used to be, but it got taken down), so the only way you'll get to hear it is if you buy the DVD (which I highly recommend!!!).
