MinionTV are a 5-piece instrumental band from Liverpool, UK and their "A Show Of Hands" is the perfect example how to create simplistic, yet very effective atmospheric track. The song is taken off their 2012 album called The Last Projectionist. Last time I checked, I still had my hearing, so it strikes me how could have I missed such an outstanding record!
The way the instrumentals belt slowly out while carefully stacking on each other - priceless! It won't take you more than a listen to realize we're dealing with musicians who clearly have an idea what's going on!
