Grammy-nominated exploratory rock band Baroness return with their most ambitious work to date, fifth album Gold & Grey. Set for release on the band’s own Abraxan Hymns, Gold & Grey spills triumphantly past genre barriers, their anthemic alt-metal hooks ricocheting between the circuitous twists of prog and jazz, the moody swirls of space-rock and noise, and the hypnotic pulses of trip-hop and 20th Century minimalism.

“This is the most clear representation of the artistic vision I have for the band that we’ve ever done,” says Baroness vocalist, guitarist and founder John Baizley. “I’m surprised that we got as far with it as we did.”

Baizley sees the diverse, adventurous album as a “lateral step” from the streamlined, immediate guitar-rock of the band’s last release, Purple, championed by Rolling Stone, Pitchfork and L.A. Weekly as one of the best metal albums of 2015. Gold & Grey works like a melodic puzzle, melodies and harmonic ideas borrowed, repurposed and reinterpreted across three sides of vinyl. Lyrics are full of sonic Easter eggs; unorthodox prog is hidden inside the most accessible songs; tunes emerge from swirling chaos and dense layers of sound. The album is given color by strings, glockenspiel, tubular bells, piano, synthesizers and even field recordings of the chaos after a transformer blew up outside of the recording studio.

“The term I kept using was that I wanted to create something that was more kaleidoscopic than our former records,” says Baizley, who embraced the wide lens and limitless journeying of artists like Pink Floyd, Neurosis, Massive Attack and Scott Walker. “We were trying to say something new with our instruments, with our sound intact, with the spirit of the band intact, but not applying the typical conventions when possible.”
