Music

In all the navel-gazing about new genres, breaking acts, what's cool, what's not and general hipster chin-stroking - it's easy to forget what music is really about and how it has the power to break down the boundaries of genres, generations, backgrounds and cultures.

I'd never heard of Naturally 7 until I saw this. They are a New York based a cappella group that only do covers. Watch below as their impromptu performance on the Paris Metro slowly takes effect on some of the glum Parisian commuters around them (regardless of background).

This really isn't my style - yet it made the hair on my bones stand on-end and put a smile on my face.

That's the power of music.
