Good. Kind of mild in comparison to a true child prodigy like Mark O’Connor, who was winning national competitions at age12 and 14.

Mark was and still is quite an amazing player over the years. The track you posted is Dixie Breakdown, at the Winfield National contest. The judges, btw, were: Doc Watson, Norman Blake and John Hartford.
For jazz/bluegrass taste here he is with some serious masters (Bela Fleck, Jerry Douglas, Mark Schatz) and giving one an idea of how large a guy he grew into, giant really- doing Chick Corea’s “Spain”— excellent.

Sandra Bae is a lot easier on the eyes.
Although I am a banjo player, I prefer Andy McKee to Earl Scruggs or Lester Flatt.
