American composer, Phillip B. Klingler, better known as PBK, has been active in the experimental music underground since the 80s. His work first became known through the homemade independent cassette culture scene of the 1980s, though later releases have also been in compact disc and LP format. His work has correlations to electroacoustic, classic industrial and free jazz genres. His compositions are created using extreme turntable manipulation, sampling, analog and digital synthesis. Improvising spontaneously and with little preconception, PBK creates pulsing, dense soundscapes of unknown sonic origin.
