Vertigo Index make no effort to hide the direct influence Discordance Axis had on them by naming their band after one of DA's songs, and the small army of Carcass clones that were exhumed after that group went tits up only solidified them as the seed to the over-saturated (and ridiculous) gore-grind genre that's still expanding today. There's a whole generation of people out there who respond to the word Godsmack with a reference to a shitty hard rock band that thinks they're better than they really are and not the bad-ass palm-muted withdrawl-trip that slaps you in the face halfway thru Alice in Chains' Dirt!
So what's wrong with indulging in something that sounds exactly like something else if that something else is done being? Nothing I suppose, you could argue it's sort of an easy way out - like covering a song note for note that was already popular once. But you could also argue that it's throwing a bone to a whole group of fans longing to hear something new that sounds like something old, and then letting them decide if they want to chew on it. That's what Wrong have done.
Helmet - lets face it, Helmet just isn't the formidable figure that they once were, and it isn't necessarily because they've been ripped off to oblivion by a genre of lemmings. They're still active and putting out music, but from what I can gather most people just can't get over that holy trilogy that is Meantime, Betty, and Aftertaste. Wrong offers you the option to go back to that in their debut E.P. Stop Giving. The catch here is that you need to get past the pneumatic roof nail in the eye that that isn't Paige Hamilton singing, and these aren't his songs, and this indeed isn't Helmet... So the question is, can you indulge?
