Otherwise the history just gets completely flattened out, and people imagine that everything was always available and accessible. One of the things that struck me was the way in which the landscape of experimental music seemed different at different points in time, on the basis of where one was situated geographically, if one had access to live performances, and what was released at a particular time.

The instrumental pieces are compositions, certainly, although that's not the language that I instinctively use. They're not scored, and arrangements are often arrived at collaboratively. I always choose to play with people whose input I desire.

The word "archive" seems so reassuring, but I'm not sure about these things that are now being called archives. Is anything lost by the fact that the word has come to mean so many more things.

Records have always been the most extraordinary form of time travel for me, and that's why it matters to know when something was circulated, and if it had an audience of five or 50,000.

If the records that I make have one thing in common, it's that there is little recapitulation, and the idea is that it should end in a place very different from where it began, and that you've heard musicians undergo a change or be irreversibly transformed.

The question of art songs always came up with Gastr del Sol. I think Jim O'Rourke had it right in being clear that there's a tradition of art song - Ives being the touchstone for the two of us - and what we do doesn't belong to it. It wasn't important to advance those kinds of distinctions, but clearly he thought it was fanciful for anyone to speak of what we were doing as being in that tradition.

My experience that undergirds that observation comes from punk, where people might have scraped together the money to be in the studio for an afternoon to make a record. Punk isn't a music that you think of as chance-based, but exigency has a lot to do with it.
