Montreal-based exploratory post-rock trio Big|Brave have premiered their forthcoming full-length, Au De La, over at Noisey. The album will officially be released Friday, September 18, via Southern Lord. Pre-orders can be found here and here. The record features an unconventional approach to the post-rock style that almost verges into avant garde territory. The album features massive drones, minimalistic rock passages, colossal, noisy marches and stunningly haunting Björk-esque vocals. Check it out for yourself here.
