Make this beatboxed cover of 'The Phantom of the Opera' the cool video you catch today

Okay, you thought you knew Andrew Lloyd Webber's The Phantom of the Opera. But this beatbox version of the musical's eponymous song is unlike any other cover out there.

Singapore beatboxer Dharni Ng starts out the video with the song's iconic bassline, before Polish soprano Edyta Krzemień sings over his beats.

Krzemień's amazing whistle register makes this one to watch, but I especially loved the part where they sync up short, staccato notes leading up to the climax.

Just gorgeous.
