'Rudolf Eb.er has released more than 100 CD's and albums internationally, and is considered as one of the leader in the noise and experimental vocal scene. Rudolf Eb.er, born austrian and grew swiss, is expert in scientific illustration, martial and therapeutic arts, and is founder of the audio-artists and aktionist collective Schimpfluck in 1987. Early sonic studies examined the importance of timing, the power of silence, and developed shocking and confusing-precise cut-up compositions, 'aural alchemism', of documented extreme-situations, psycho-field-recordings, and direct actionism - an actionism of the unexpected.

Regarded as 'art-brut shamanist', Eb.er's path leads down thru the unconscious, deepest regions of human psyche and animal instinct. Abreactive outbursts arranged in the high art of timing, as mediated in disciplines such as kung-fu, confront all senses with existence - and open up the way to the higher being.

Runzelstirn & Gurgelstøck is another name for Eb.er's psycho-active audio-art and 'psycho-physical tests and trainings', performed and produced global. Eb.er, currently living in Japan, increasingly focus his 'purification rituals' on breathing exercices, concentrated chi-energy and shifting psycho-magic to enter the super-consciousness, the nondualist awareness of 'ultimate reality'. Extreme Rituals contains two raw surgical wild tracks of 17 minutes, masterworks of intensity. Recorded and decomposed by Rudolf Eb.er in Osaka in 2011.'
