Oh, the outcome is quite intentional.
I can crack on Shepp for some things (like long-windedness) but lack of intention would never be one of them.
If it was not controlled or intentional to one degree or another, the flow of the line would dissipate or otherwise break down.
Shepp has always been as much a painter as he has been a player, and a still-life painter is just not what he has done, ever.
Now having said that, he did have a series of physical issues that affected him. But rather than struggle against them, he embraced them and intentionalized them. That's why the line keeps flowing, and that's why it's intentional and controlled.
That's also why those Venus records have such emotional power to me. They're true, because life doesn't always pull its punches. Sometimes they land, land hard.
But oh well about that, right?
