BPM II is the second release by the British electro-acoustic group Fendahl, and the first in a four part series of albums inspired by the pioneering work of Czech psychiatrist Stanislav Grof. The series explores Grof’s cartography of the deep human psyche, in which he describes four experiential patterns which emerge at the boundary of the individual and the transpersonal, typically revolving around the physical experience of the birth process - the Basic Perinatal Matrices or BPM I-IV
It is recommended to experience this recording at moderate volume in an otherwise quiet, comfortable environment, marked by the absence of bright lights or other intrusive distractions, to encourage undisturbed and focussed listening. Individuals who have chosen to experience this work in its intended Compact Cassette format are advised to ensure that the auto-reverse function on their stereo component system is selected, to allow for uninterrupted playback of the material.
Listeners may find themselves trapped in a world that is collapsing. Initially an insidious threat whose source is mysterious may progress to paranoid ideation, leading to visions of whirlpools, vortices, consumption by octopi, pythons and giant spiders etc. The atmosphere is one of extreme emergency, which may manifest in an increase of pressure both physically and psychologically to unbearable proportions. Listeners may experience the realisation that the agony of birth equates with the agony of death, including but not limited to feelings of guilt, persecution, memories of injury, incarceration, drowning, disease, ridicule, humiliation, interrogation and rejection.
