All the artists in that series do their own thing with the Paintbox. I don’t recall how or why I watched the Hockney episode and not the others, but I’m happy to find them on Youtube. Every artist finds their own unique voice in there, but I love how excited Hockney gets. His joy seems more obvious than other artists. Larry Rivers was also a lot of fun to watch.
Anyway, I remember enjoying the experience of watching it enormously. I was probably just too busy to even notice the others when they were broadcast. I don’t recall even realising it was a series.
There was also a 90 documentary about Hockney broadcast a few years ago. There were so many styles and media in there, but some, like the Paintbox, weren’t even mentioned, but at least the iPad stuff got sqeezed in there, however briefly.
I guess some artists, like Hockney and the Vasulkas, did so much that 90 minutes isn’t close to enough time to cover all of it well.
