The little 9 year old girl is a joy to watch.
The 15 year old lad has a great technique, but it just leaves me cold.
I remember many years ago when I was playing second guitar in a band and we were auditioning for a bass player, the guy was a bedroom player and had some seriously good technique, as demonstrated while we were setting up, unfortunately, when it came to playing with a band he was just awful, bad timing, couldn’t lock in with the drummer.
