About "Unidentified Again" : "I first met Jim O'Rourke in 1989. We corresponded by mail and would talk on the phone frequently. Jim was in college at that time and he was very excited about music. He sent me mixtapes, we would talk about his love of Van Dyke Parks, his work with KK Null or Henry Kaiser. I also remember he sent me Godflesh' "Streetcleaner" album which he likened to King Crimson's "Red". Jim's soundwork was always special and I released one of his compositions on my Assemblage" compilation tape in 1990. We talked about collaborating, but then my situation changed suddenly and in 1992 I moved to Puerto Rico with my family. My life got complicated and I fell out of touch with a lot of friends while there. By the time I got back to the States things had changed for Jim as well, and he was in a nomadic phase, drifting around, performing a lot of concerts around the world, but a letter I sent to his parents' address eventually reached him and in 1997 he wrote back and replied that he was only able to finish about ten minutes of electronic music a year. Still, the interest in collaboration was there, though Jim was very busy and things did not materialize in the collaborative direction for us.
That was the last time I heard from Jim for 15 years, until something coincidental happened in 2012. My cousin runs a label and put out a record by Merzbow. One day my cousin informed me that my old buddy Jim O'Rourke had ordered the album. As I was assisting him with shipping copies of the album, I wrote a note to Jim and threw in a couple of my CDs along with the LP.

Not too long after that, Jim and I were in contact again. As is always the case with us, we fell into vigorous conversations about music and everything else - and again the idea of collaborating occurred. Rather suddenly Jim surprised me with source material I could use. I immediately went to work on it, with the idea that approximately 40 minutes would just about be ideal for an LP project. The sound material Jim sent was likely composed on his Serge modular synth. We'd been discussing synthesizer heroes of ours - Jim sharing his love of Roland Kayn's expressive work and I'm always going on about David Tudor. I worked on the first two mixes, but I dug Jim's sources so much I didn't do any kind of manipulation on them. I built audio environments for his sounds to live in, and they do sound alive, like synthetic landscapes with birds or animals of some primitive, or alien, origin and, of course, also huge drones that could be electrical storms. I sent Jim my own sources and he came up with two beautiful mixes, each quite different from the other.
I'm very pleased we finally got to do our collaboration - even if it took a quarter of a century to make it happen." Phillip B. Klingler, April 2015.
