New releases last eight weeks: Progressive Rock

Review: The third full-length from Los Angeles-based progressive, jazz-tinged post-metal giants Intronaut was originally released in 2010 and celebrates its 15th anniversary this year. Further embracing the fretless bass, jazzgazing style of its 2008 predecessor Prehistoricisms, the material found on Valley Of Smoke was the first from the band to slightly eschew the use of exclusively harsh vocals and instead utilise the harmonious cadences of dual vocalist/guitarists Sacha Dunable and Dave Timnick, conjuring a hypnotic balancing act reminiscent of the synergetic fusion of Alice In Chains' Layne Staley and Jerry Cantrell. Featuring Tool bassist Justin Chancellor on the epic title-track, providing double bass flourishes, as well as the pitched glitching vocal processing similar to that of progressive death metal legends Cynic (both of whom the band would subsequently tour with), Intronaut have always deserved to be spoken of within the same breath as the likes of Mastodon, Baroness, Deftones, Hum, and any other respected boundary pushing group connecting the mercurial dots between grandiose, conflicting sonics.
