Russell was prolific, but was also notorious for leaving songs unfinished and continually revising his music. Ernie Brooks said Russell "never arrived at a completed version of anything." Peter Gordon stated, "his quest wasn't really to do a finished product but more to do with exploring his different ways of working musically." He left behind more than 1,000 tapes when he died, 40 of them different mixes of one song. According to Russell archivist Steve Knutson, the musician's estate consists of around 800 reels of 2" and ¼" tape, "another few hundred cassettes, several dozen DAT tapes, hundreds and hundreds of pages of song lyrics and poetry".
