Two astonishing and odd videos of drummers drumming.
The first is Max Bacon - drummer with the Ambrose Orchestra and perhaps most famous for singing Cohen The Crooner, The Crosby of Mile-End - plus Victor Feldman and Freddy Crump. Arguably there's more Freddy than Max. (The drumming starts at 2:57)
And this is a clip from the film Gonks Go Beat and features drummers like Ginger Baker and Bobby Graham dressed a little like Star Trek characters and drumming in unison. (The drumming starts at 1:45)
