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 danger of these collaborations across disciplines is in having too strict of a division of labor - in my case, of getting stuck doing the music. When I make an album, I write music, I write lyrics, I come up with the visual design, etc. I get to do all of that stuff.

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.

The word 'archive' seems so reassuring, but I have a lot ofconcern over the longevity of documentary materials.

As there are more online archives of improvised music, it becomes more like the daily practice of playing it. It lessens the idea of there being masterpieces of improvised music through benchmark recordings.

Chance in music doesn't have to involve the I Ching or rolling dice or throwing yarrow stalks. It can involve an out-of-tune guitar, or other impossible-to-replicate moments of awkwardness - even more so than an awkward, out-of-tune live performance, because there's something incredible about the way that an out-of-tune guitar becomes part of the song on a record. I won't be precious and say it's part of the composition - that's nonsensica l - but chance occurrences are so crucial to what's distinctive. It's the fingerprints all over so many of these recordings.

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.
