Awesome alt violinist Lindsey Stirling and a capella group Pentatonix cover Imagine Dragons’ “Radioactive" using nothing but their voices, a cello and a violin.
Yes, that dude is beatboxing and playing the cello at the same time.
The song is also available for sale: https://itunes.apple.com/us/album/radioactive/id637055735?i=637055958&ign-mpt=uo%3D4
