May God rest the souls of all those lost in this terrible tragedy

Russia, and the world, has suffered a massive cultural loss.
The Alexandrov Ensemble army choir, formed in 1928, is vastly popular, and will have to be reformed almost from the bottom up. It's considered one of the greatest male choirs in the world. It's known for performing traditional Soviet and folk songs, and modern hits as well (everything from Queen to Lady Gaga).
