Hailing from Montreal, Population II are a power trio with a sprawling and muscular sound that traverses hard psychedelia, rambling blues, and sludgy proto-metal, while nodding to avant-garde jazz and blown-out garage rock as well. Their earliest releases leaned into the sprawl, featuring sidelong tracks that ebbed and flowed in a wash of fuzz and thunder. Once they began to pare down the excess, what was left was more compact nuggets of left-field psychedelia. This process started on 2020's À la Ô Terre; their fourth album, 2023's Électrons libres du québec, is even more song-oriented.
