The etree is a community of FTP servers that host digital audio files. Etree distributes concert recordings of bands that allow the audio taping and trading of their shows. Primarily, the etree deals with bands such as Phish, The Grateful Dead, and others who wish to keep their live music free and accessible. Any band that allows concert taping and distribution on an even-trade basis is welcome material for the etree!
