Rob Brezsny has this to say, directly to me:

A bottle of Chateau Cheval Blanc wine from 1947 sold for $304,000. Three bottles of Chateau Lafite-Rothschild 1869 went for $233,000 apiece. The mystique about aged wine provokes crazy behavior like that. But here's a more mundane fact: Most wine deteriorates with age, and should be sold within a few years of being bottled. I'm thinking about these things as I meditate on your long-term future, Sagittarius. My guess is that your current labor of love will reach full maturity in the next 18 to 20 months. This will be a time to bring all your concentration and ingenuity to bear on making it as good as it can be. By September of 2017, you will have ripened it as much as it can be ripened.

And frankly, I like this. That I've finally begun writing music again seems to frame the above rather neatly.
