Hey Mesh ,
Back in the day I was friends and played some recording sessions with a bass player named Tony Oppenheim ...
Tony wrote the book on how to play slap bass

his book was called Slap It ...
Back to your OP ....That's some cool stuff . I enjoyed watching those Bass Vids
I'm all dude'd out after watching him play .
There is something in his eyes that's a little psycho and I need to see a female Bass player
Here's a couple of the young and up and coming Ladies I enjoy watching play the bass ...
this first one has such a lovely presence and wonderful energy ...she reminds me of a delicate flower ..
I feel so bad that I keep wishing she would pull a Sharon Stone type of move like in Basic Instinct
This Gal here I can look at all day play the bass ...
maybe the guy in your opening post stands a chance on getting to know her

he's young and he can sure play a mean bass ...
all the best ,
Kenny
