There isn’t much information around on Spontaneous Sound, an alias of musician Christopher Tree. Regardless of one’s opinion on late-20th-century appropriation of a dog’s breakfast of ‘eastern mysticism’, Christopher Tree admirably spent much of his time practicing early forms of music therapy, playing concerts for prisoners and the less than privileged, and hosting youth workshops. Of the hundreds of concerts he played, only a handful of recordings have appeared. Perhaps best known is the live recording of his performance At The Cathedral Of St. John The Divine, co-released in 2002 by Quakebasket (recently resurrected) and Locust Music (since AWOL). There is also a recent CD of studio recordings on Cardas Audio.As for releases contemporaneous with his most active era, I can find only two. An 8″ flexidisc that seems to be in promotion of an album that was never released, and this - the self-titled and self-released Spontaneous Sound. Comprised mostly of percussive elements with the odd woodwind, the music is commendable for its dynamic range and diverse song structure – think Michael Ranta rather than Gamelan Son Of Lion. The quality of the recording itself, and duration of its works, leads me to believe this is a studio recording as opposed to a live take as on At The Cathedral… Good music and worthwhile seeking out.
