Professor Paul Whitty has been capturing the sounds of amateur and grassroots football for many years. He records the sound of lines being drawn on pitches, goalies kicking mud off their boots on goal posts and the incandescent rants of outraged touchline supporters. Interspersed with the pings of balls against posts and shouts of "MAN ON!!", he captures the sounds of birds and traffic that surround football on parks and recreation grounds. It's a terrific way to spend half and hour.
