Randy Greif is a music composer. He has been pushing the boundaries of auditory arts, often incorporating electronic, computer and concrete music with spoken word, "sound theater", and field recordings. Location recordings in places such as Amazonia, New Guinea, and Thailand have found their way, often manipulated, into some of Greif's music, branding it as "tribal" electronics. Trademark styles are dense layers of atmospherics, cut-up vocals, and shifting minimal rhythms.
