"Like its two predecessors, this third set dances between light and darkness, exploring the parameters of Röyksopp's hallmark sound on highlights like the glacial, string-laden "So Ambiguous," with its very understated vocal from Irrepressible, and the menacing, nearly 10-minute instrumental centerpiece "Speed King." At its peak, the latter track feels like an Antarctic rave or the soundtrack to a high-speed snowmobile chase, proving that Berge and Brundtland can still bring the thunder to the dancefloor ... Detroit's Maurissa Rose adds a rare bit of American flair to Röyksopp's overwhelmingly European palette on "Feel It," and Londoner Pixx helps end the project on a high note with the dynamic "Like an Old Dog." Standouts aside, Profound Mysteries III feels like the weakest link in this ambitious, year-long project which, while exciting to behold, probably could have been condensed into a one exceptional album".
