Any die-hard fan of progressive rock/metal should know this album by now: Porcupine Tree’s In Absentia—arguably the best album the band has put out to date. But while Porcupine Tree is on hiatus, and Steven Wilson’s general focus has shifted to his solo work (and a Blackfield album that he had little to no input on), one can’t forget the impact that this album has had on the rock and metal community. In Absentia was a lot of things for a lot of people. It arguably blurred the lines between prog rock and metal. It set a new standard for what Steven Wilson and his band were capable of musically. And it remains one of the seminal progressive albums of the modern era.
