When four young lads first got together in Liverpool, they had no idea that some enthusiastic yelping and screaming, two guitars, bass and drums could spark a revolution. They didn’t suspect that four working class chaps could form a rock ‘n’ roll band and make a set of records that would influence countless bands and encompass multiple styles, and write songs that people would still be enjoying decades later. This band, of course, is Carcass. Yes, there was that OTHER band, The Beatles, who did all those things, too. But this is an extreme metal blog, and in this existentially hellish alternate universe, Carcass may well be The Beatles. As Carcass prepares to undertake a tour with “love ‘em or hate ‘em” blackgaze critical darlings Deafheaven, some of you may be wondering how we got here. Well, keep in mind that The Beatles’ own John Lennon spent a lot of time with more out-there avantish types in the 70s, too. He cranked out some borderline unlistenable noise with Yoko Ono which is, frankly, far less palatable than Deafheaven; but there’s admittedly a lot of screeching in both. If you’re surprised that Carcass made this choice, well, shows how much you know about Carcass. Wait—John Lennon and Deafheaven what?
