I could watch and listen to Ben Oki for a long time. In this one, you get to watch the old master wiring, and, as a bonus, hear a story about John Naka; another old master.
FYI: John Naka was considered the dean of American bonsai. He died in 2004. Bonsai Today issue 93 features a special on Mr. Naka and you can enjoy his sketches in The John Naka Sketch Book (The National Bonsai Foundation). Two other noteworthy Naka books are: Bonsai Techniques one and two (Bonsai Institute of California).
