btw. this is from another John Mclaughlin interview from All About Jazz:
“So, anyway, my manager had heard about this kid and we were speaking one day and he said, ‘You know I’ve heard this bass player,’ and my antenna went up, and I said, ‘Let me hear him, whatever he’s got,’ and he played me something that was just rough, a demo. I called him right away and said, ‘Listen, come down here, I’m in the middle of recording, and there’s this tune you have to play on.’ I’d already written ‘For Jaco,’ and I didn’t even know who was gonna play on it, I really didn’t. But this tune was so much for Jaco and it couldn’t have been more timely. I heard this kid play, I couldn’t believe it, so I got him down, and we played and we recorded and, for me, he’s the new Jaco [Pastorius]. He’s twenty-two now, it’s terrible! And he doesn’t even read music, but he’s got amazing ears. Harmonically, I say, ‘Do you know this chord?’ and he says, ‘Yeah, yeah, yeah,’ or ‘Let me hear it,’ and boom! he’s got it. Amazing, like Wes Montgomery. Incredible.... "
what ever happened with the band afterwards and why they changed bass players, is another story... but getting these words of praise from John Mclaughlin, who played with the best of the best bass players, shows that he is aware of Hadrien's talent. I wish more people were as well, and instead of always criticizing and teaching about the righta and wrongs (as is music was an exact science), would look for the diversity and beauty in music and its players.
