My brother showed me this and I thought it was pretty cool. Macy's in Philadelphia has one of the largest pipe organs in the world and every day at noon they play for the punters. The Philadelphia Opera thought it would be cool to send 200 of their singers in there to mingle with the oblivious crowd and randomly join in with Hallelujah Chorus. I'm not religious but it's still pretty cool
also listening to masta mic he samples his on voice to make cover tracks of other peoples music, have to watch them all the way through
Sorry cant post video off iPad , but could someone else for me please The Lumineers - Ho Hey What a album
