My dive into the more experimental/progressive side of metal over the past couple of days has unearthed some impressive stuff. This album in particular really stands out to me. The whole album is just one single epic 60-minute piece that throws riff after riff at you, some string sections, haunting female vocals and even some saxophone. Despite its ambition it never feels dragged-out at any point and is remarkably well-executed.
