Brad Close BBb Contrabass Trombone demonstration, Blake Cooper demonstrating the "farty sizzle"

This one of a kind BBb contrabass trombone was commissioned by me and build from scratch by Brad Close (www.brassmedic.com) . You can read more about it at my website (www.brassark.com). It has valves in FF and DD and plays very loud, but also very soft.
