actually he is a very talented musician. His shtick in the videos is people send him lines or solos as a challenge and invariably he can play it and nails it.
Here's one where he challenges another "pro" bassist. It looks like they are friendly competitors and just playing up the "rivalry" for views, Some incredible bass playing in this video. I'm not a big fan of slapping and tapping on the bass (maybe 'cause I'm no good at it) but still you have to give them credit.
