In the typical world of heavy metal lots of people want everything to be perfect. As honest as I can put this there is no need for such a thing. It should be about as long as you enjoy it that’s all that matters. So what if the sound changes a little because the band decides to go from classic hard rock to a heavier sound? Or the band members change, or even the band itself has a strong visual images and they’re either a new band or a legendary band that has been around for decades.
Let me put it to you with the most recent thing I’ve been noticing.
Some Metalheads claim they will listen to any metal band except these guys. A few good friends of mine who live overseas from me like this band. I’m not a huge fan of them, I only heard one song by them and thought it was pretty good. Also I thought their image was pretty cool. I like Gothic style. But why say shit like that when you haven’t even given a band like this a chance? If I started listening to these guys more often and started to really like them I don’t want people to judge me for it. So some metal musicians choose to look more like Dave Mustaine and James Hetfield while other metal musicians wanna go hardcore with the image like Gene Simmons, Mr. Lordi, Abbath, etc.
