Explosions in the Sky are my favourite post rock group, there pretty goddam amazing imao. I could never get into other post rock banRAB such as GSYBE or Mogwai as I found them to be overblown and pretentious. But theres something about Explosions in the Sky, a kind of down to earth honesty that prevails through all there music (probably down to the fact there a band, as opposed to an orchestra), and its certainly some of the most emotive instrumental music I've ever heard. There great to chill and work to.
