There's always good music, if you look around and listen around. But just sometimes the gates open, and you don't have to look around for it, because it's there on main stage. And there's a changing of the guard in the music business, and it stays like that for a short while. And then it goes off, and the main stage is full of drab wannabees. It probably happens every 11 years or so, and coincides with sunspot cycles or something. Right now I suspect is a low point, but it'll come round in time.

Meanwhile, out in the folk world you never have to look all that hard to find good music. And when you're tired of looking, you make it yourself, and if it isn't that good all the time, it helps you recognise what is good. (And "good" in music means, I think, you want to hear it again; and you still want to hear it again years later.)
