My attempt to squeeze 29 Opeth songs into three minutes. Some parts are kind of hidden, but it’s possible that you’ll recognize everything. All you hear is Opeth, although I have pitched and time streched some parts to fit in with each other (plus equalization, reverb etc.)
The picture is taken from the “Photoshopeth“ thread in the Opeth forum (this particular one, along with many of the others, is made by the great Anvar), take a look if you haven’t already :)
