_tunic_, you beat me to it. I was planning to upload my rip of the XFM session. I've been quite busy so I'm glad and thankful you've posted this here, too.
By the way, it wasn't Tramped By Turtles joining Low at the New York show, this time it was ACME: American Contemporary Music Ensemble.
Also, Planet Claire uploaded Low's Planet Claire session from October 24th, 2004 to their bandcamp page yesterday. It's only available for streaming at the moment, but a link to download lossy files is located there, too (It's been active for years at their official website). I asked if they would please provide lossless audio, and they said they'll try to figure that out.
