London's Capital Children’s Choir has been singing since 2001, growing from four 10-year-old girls to 120 kids between 7 and 18. They've since performed for the Pope and the Queen, sung onstage with the reunited Spice Girls and punk-rockers Anti-Flag and even record at Abbey Road.
But perhaps their neatest trick is their latest choral cover of the seemingly impossible to cover a capella Crystal Castles, emulating the synths and drum machines of "Untrust Us" with only their voices and hands. We've also included the original Crystal Castles version with an unofficial (but officially awesome) fan-made music video right below.
