Rangers is Joe Knight from Dallas, Texas. He makes cosmic tape collages that are heavily rhythmic and psychedelic. He mixes bits and pieces of heavily processed and treated live recordings of guitar, keyboards, bass and percussion with samples of a wide variety of media (commercials, movie samples, jingles, etc.) and found sounds, culminating in long continuous pieces that are truly unique and captivating, but never boringly academic or overly abstract.
