I think that generally Lacuna Coil haven't "sold out"--they just need a new producer. Their albums since Comalies have all been SOO polished (almost over-polished?), and I think that has affected their sound. They sound way more mainstream because of how polished their songs are. I liked Karmacode and a few songs off A Shallow Life, but I admit Shallow Life was preeeetty "mainstream"-sounding. I almost gave up on Lacuna Coil after that, but decided I'd give Dark Adrenaline a try. And I think they're going back to what they used to be.
Expect a full review to come later, but for now here's the video for the extremely catchy song, "Trip the Darkness!"
