The 4th Deafest full-length album is an instrumental composition broken into two sides (Glen/Precipice) with each side written in 3 movements.
"The sweeping, layered guitar compositions are alternately sunlit and beclouded, soaring and storming. At times rapturous and at others wistful and somber, the songs are always alive with passion, and they have the capacity to pull the listener headlong into their creator’s vision and become spellbound."
-No Clean Singing
"Deafest has been steadily improving over the last decade and Glen and Precipice shows the project at its strongest yet. This is atmospheric black metal that doesn't need to resort to cheesy synths and interludes to get its point across. Instead, the album offers insight into Ambler's admiration of the Rocky Mountains and the breathtaking awe those mountains possess. This is a quite remarkable effort from a project that should get way more attention that it does."
"'Glen and Precipice' is an astound work of art, that I hold very close to my heart, there are so many emotions captured within the riffs of this short masterpiece. I very much truly mean masterpiece as well; this album will take you on an emotional journey through the valleys, "Hollers" over mountain tops soaring high into the bright sunlight to leave you back down in the valley in the furthest reaches from the warmth of the sun. Where your heart will ache and mourn for our beautiful earth, as you sit back and watch humanity destroy the one thing they have left; then when the chords and the atmosphere lifts your spirits again, you'll sit high above the mountain tops at one with nature. A new found respect for our home."
"What I really love about this album, and of course all the other releases before, is the passion within. You can feel the love for the mountains, their precipices, scraggy landscapes, highest snow-covered peaks and vivid streams in every single track."
