Transposing the Darwinian figurations of evolution into the dynamic simplicity of an ideogram we find a man hanging from a tree: his eyes dark as the abyss he battled and then became. Dead branches arc downward diverging from ones plunging upward while fruit gleams over Man's head in altitudes inhabitable only by the Phoenix, and a gnarled trunk split by lightning diverges into roots that strangle each other between the dance of worms.
The oldest and simplest of families of instruments is also the largest and most diverse. From Charlie Parker to The Sex Pistols, percussion has been the common element to and the driving force behind most forms of music in the last hundred years. The instruments can be metal or wood, outfitted with leather or strings; they can be carried, sat behind or worn. They can be simple and homemade or complex and expensive. Watch tourists gather around a guy beating on plastic buckets on a New York subway platform and you'll get the idea: Drums are everywhere, and are made from just about anything.
