Orthrelm are an avant-garde metal band from Washington DC. Their latest album, OV, is either a masterpiece or complete bullshit. It consists of one song, titled “OV”, that is 45 minutes long. It’s extremely repetitive and grating. But here’s the thing about avant-garde: Can you be sure that the band is making satirical music, or are you just not avant-garde enough? Who knows, man? I’ll let you ponder this question as you spend the next 45 minutes listening to OV.
