It was inevitable that Norwegian ambient minimalist Geir Jenssen (Biosphere) would explore the microfibers of jazz. After a dozen years of pioneering quiet, cold-filtered electronic music that invoked his Arctic surroundings, Jenssen now applies his techniques to ECM-style sounds (think Keith Jarrett, Ketil Bjørnstad, etc.). Unlike his jazz-noodling countrymen, Jenssen sacrifices none of his contemplative ambient climates on Dropsonde, his fifth release for England‘s austere Touch label. Whereas Jenssen‘s attempt to “bliss out” classical music samples and loops on ‘02‘s Shenzhou proved lackluster, the jazz snippets used on “In Triple Time” and “Fall In Fall Out” add tension to a recording that will leave you mesmerized for repeated listens.
