THE PARADIGM-SHIFTING FOURTH STUDIO OPUS FROM THE NORWEGIAN PIONEERS - PRESENTED ON DOUBLE GATEFOLD BLACK VINYL FORMAT, INCLUDING A RETROSPECTIVE LOOK AT THE ALBUM COURTESY OF WRITER JEFF WAGNER. 'Themes From William Blake's The Marriage Of Heaven & Hell' was the fourth studio album by Norwegian experimentalists Ulver. Having been known for their more folklore-tinged black metal compositions on early studio releases, in late 1997, mainman Kristoffer Rygg invited keyboardist, sound conceptualist & composer Tore Ylwizaker into the collective & together they devised a plan for The Blake Album; an altogether far more adventurous endeavour than prior releases.
