That being said I agree with an earlier post that a player like Hadrien, IMO, would be better served touring as a primary soloist in his own band, with another 'BASEplayer' in tow to play supportive lines. His amazing technique obviously has a lot of fans and I'm sure he could build a career off of just that.
That's what Jeff Berlin does.
And it works for him. A horn player trapped in a bass players body.
