I understand that music in general is a very personal thing but I feel like I have to respond to this, lol. While I do agree that Hadrien does seem to make his music for other musicians I think he's far more than a chopsmeister. Yes, he can blaze across a fretboard at Mach 2 but I find him to be one of the most tasteful and musical bass guitarists around. I think he falls right in line with this "new" generation of bassists (Tony Grey, Janek Gwizdala, Richard Bona, Matt Garrison) that improvise in similar ways to horn players in their phrasing and use of dynamics and sound fantastic doing it. Hadrien's solo album is one of the most well composed, beautiful sounding bassist albums out there. You can tell right off the bat that it's a bass album but he does it in such a way that it isn't obnoxious or grating, everything just falls into place.
All that said, I do believe that if Hadrien were put into a band "for the people", people being non-musicians, I feel like he could really turn some heads. That's just a gut feeling though.
