I've been to a few clinic but the one that always stuck in my head until now is Mr. Billy Sheehan's clinic in 2000.
I think it's because of his casual and funny presentation and yet amazingly presented small licks that made audiences went nuts. Well I know he's already famous but hey, I think it's a good clinic overall.
The sequence is something like this:
1. His history with bass
- He told the audience of why he picked up the bass. His childhood neighbor is a cool huge dude, rides a harley, always has new girls around him, etc. And he plays Bass. So Mr. Sheehan said: "I want to be like that." Then the hall is filled with laugh.
2. How he approaches music theory (scaryyy-musiccc-theoryyy he said, with his funny face)
- As we know he isn't the most theoretical player out there but he encouraged us not to afraid of the theory it will eventually comes to senses and somehow we (younger audiences) will have our own natural urge to learn them as we grow.
3. How uncool the music is without bass and the purpose of bass player
- Music is playing on the background without bass while he was talking about how important the bass is and suddenly he stood up and play along with the music. We realized how soulless the music was without his bass
4. His personal favorite techniques and approaches.
5. Endorsement session by Yamaha lol.
6. Q&A session: I realized that Mr. Sheehan is a pretty humble dude. He didn't try to answer every single thing and humorously and humbly skipped some stuff that he doesn't know (like someone asking about double-thumbing.)
7. Finally a solo Mr. Big's To Be With You with all audiences singing to wrap up the night.
That's my favorite clinic out of few. Hope it helps you getting an idea of yours =)
