Post-rock can be divided roughly into two arms: the stuff that fits easily on film scores, and the stuff that doesn’t. The former is no less artistically viable (Explosions in the Sky!) than the latter: it’s just an easy way to differentiate the priorities of the band in question. Glacier does not traffic in triumphant earworm melodies. Instead, the band creates fully realized soundscapes that include found sound, spoken word, instruments that sound like air raid sirens, and lots of empty space in addition to guitar and drums. Some post-rock accompanies the movie: Glacier‘s post-rock is the movie.
They’ve dropped two releases at the same time: the 18-minute Black Beacon and the 32-minute Kirtland. The entirety of Black Beacon is one ominous track that sounds perhaps like night during World War II, due to the eerie air raid sirens at the beginning of the track. They move from using the instruments as soundscape tools to a prolonged section of bleak, trudging, stomping, burdened rock that is genuinely towering by the middle. It’s post-rock for people who like post-rock for post-rock’s sake. I know that seems like a self-evident statement, but Glacier is in a whole different ballgame than (IC faves) Lights & Motion: L&M is concerned with beauty, light, and airy arpeggios, while Glacier is concerned with heavy, slow, moody, dissonant things. (Their respective names are also perfect representations of their differences.)
Kirtland is a little peppier than Black Beacon, taking less time to get to towering walls of noise. Opener “You’ll Love It Here Forever” drones not by low-level buzz and hum, but by hammering the same riffs and rhythms for a good long while (like a certain post-metal band with a currently unfortunate name was fond of doing). In short, it’s got way more riffing than the former album. The 21-minute title track of Kirtland returns more to the moody element, dedicating the first minute to no more than four chord strums and some truly evocative wind noises and tape hiss. The careful construction of the background noise (again, like a movie would) sets up a very particular mood that Glacier expands throughout the track. It’s the sort of attention to detail that people who’ve heard a lot of post-rock will really appreciate.
If you’re into moody, dark, heavy, occasionally thundering post-rock, Glacier is ready to help you out.
