I am not a connoisseur of beat boxing, but this good old boy seems to have the knack…

Same guy, this time as someone’s grandfather performing in the hood…

From Wikipedia: Beatboxing (also beat boxing or boxing) is a form of vocal percussion primarily involving the art of mimicking drum machines… using one’s mouth, lips, tongue, and voice. It may also involve vocal imitation of turntablism, and other musical instruments. Beatboxing today is connected with hip-hop culture, often referred to as “the fifth element” of hip-hop, although it is not limited to hip-hop music. The term “beatboxing” is sometimes used to refer to vocal percussion in general.
