Police drummer Stewart Copeland recently posted On Drums, a 40-minute documentary about his instrument, on his YouTube channel. In the film, Copeland takes us to Congo Square in New Orleans to talk about DD Chandler, who invented the modern drum kit in the late 19th century, and interviews drummers Taylor Hawkins of Foo Fighters, Chad Smith of Red Hot Chili Peppers, John Densmore of The Doors, Sheila E, who backed Prince, and session percussion great Bobbye Hall.
