When if I first read the news on Blabbermouth.net I was just like "::30 seconds of silence,:: noooooo noooooooooooooooooooooooooooooo"
But you know? Blabbermouth.net has a history of false accusations and news so I'm not taking it too seriously yet, and even if it were true, they still haven't signed to the label yet so I suggest we all remain calm. Roadrunner always carries artists keeping the current trends alive...death metal and post thrash back in the late 80s and early 90s was the current big thing. Gorguts, Deicide, Pestilence, Obituary, Atrocity, Malevolent creation, Cynic, Disincarnate, Resurrection, Sepultura, Death, Suffocation, Immolation, Sadus etc...I don't think roadrunner would sign Opeth to their label without the band willing to compromise their sound for the current trend. If this next Opeth record is a very my arms your hearse/deliverance sounding record...I wouldn't doubt a couple tracks experimenting with metalcore breakdowns.
After all that though, the sources that told blabbermouth.net about this are probably full of shit, if not blabbermouth being completely full of shit. Don't believe it.
