Collaboration is one of the Pillars of DIY Homemade Experimental Music!
Most of my collaborations in recent years have been conducted via postal mail -- such as the soon-to-be published dictaphone assemblage album titled microcassettera, with long-time collab partner Chris Phinney. But nothing beats collaborating in person! Phinney and I collaborated in person on numerous occasions. One of my other favorite collaborators is Brian Noring.
Brian used to operate the F.D.R. Tapes label in the 1990s, and I visited him on numerous occasions in his hometown of Des Moines, Iowa. Brian and I have collaborated on more than 25 albums.
For your listening pleasure, here is "dada beat hippie noise punk raveup, an improvisation-based collab track in two parts from an album called Studies in Sound Archaeology, originally recorded in October 2001.
