5 awesome beatboxers for Thursday

What do you know about beatbox (bitbox)? Folks who make amm-yammi-boom-bts sounds? I like beatboxing very much if it's performed by real professionals in this style. Watch them, and I hope you'll like them as well. Some of them've got more than 18 mln views via YouTube, some - only several thousands. It doesn't matter when we speak about quality not quantity. I think beatboxing is not a cultural and musical phenomenon; it's a kind of life-style in some way.
