Kenny is known for using a technique called the "wind technique", which heavily utilizes breathing as an element of the beatbox routine. This creates a unique effect of audibly inhaling and exhaling while simultaneously creating percussion sounds with the mouth.
Kenny has worked with many other artists, a large proportion from outside the genres of beatbox, hip-hop or rap, including Public Enemy, Mindless Self Indulgence, Matisyahu, Squarepusher, The X-Ecutioners, Regina Belle, The Gap Band, Maxwell, Angie Stone, Stevie Wonder, Vernon Reid, and Take 6. Kenny has also collaborated extensively with his fellow beatboxer Rahzel.
In 2004 Kenny was arrested by police in Chicago. To support him beatboxers arranged a benefit concert in New York.
