The Nature of Art Ever been working on something passionately and experienced a time warp via tons of productivity? That is the artist's method. — Vaskane
This often happens. But equally, in the style of Radiohead, intense scrutiny and slow, slogging technical adjustment results in similar feelings of achievement toward the end product. — AmadeusD
Yes, both are valid approaches and I think most artists probably engage in both to varying percentages. It's seems like a trite quote, but I've always loved this which is attributed to Picasso: "Inspiration exists, but it has to find you working." So, those flow states don't require discipline, and you can certainly find yourself in one and make something. But if you are disciplined in showing up to the drawing board, the flow states will come more often and you'll be more productive. Says the artist who hasn't shown up daily to do the work in years.
I also think as I get older, I'm developing more respect for the slow methodical artists. I was never one myself, and the flow state, dramatic artists who have that flair are always more visible and attractive. I like the Debussy/Ravel dichotomy. Both pretty equally respected now, although I think Debussy is more well known, and he was the flashy flow state guy. He's easy to fall in love with right off the bat, but Ravel takes time to appreciate, and Ravel was the method man. As I get older I've shifted from preferring Debussy to now preferring Ravel. I liken it to a hot and heavy summer fling versus realizing twenty years later that you love your best friend from growing up and then get married to them.
