And the same happens to a band. After all, a band is formed by human beings, and like everyone else, they get older and their taste changes. When they are in their early twenties, they like to play heavy and destroy instruments, but when they grow up, they find it more satisfying to play softer music.
The Gathering, a well-known Dutch band has also gone through evolution, and thanks to this evolution they lost a good number of fans. Their everlasting thirst for always experimenting with different genres of music, cost them dearly. When you compare Always, their first studio album, with The West Pole, you wouldn't even recognize them. The first album is heavy, doom metal, while their latest release, is as good as Pink Floyd music, and I am not joking.
Is it wrong, or is it right that bands change? Unlike all the thirsty for money record label directors, I think it is the best option to allow bands to go through their natural evolution. Let them experiment and do what they want to do, because that is the only way how you can get the best out them. Unless bands experiment with music, there will never be something new and original to listen to. Back in their early days, Pink Floyd were classified as an alternative band. Today they are Pink Floyd, an iconic band every human being heard of! If you like a specific album from a band, and not their latest releases, it does not mean the band does not play good music anymore. It means that the band is experimenting with music, and respect that fact without pointing fingers at their previous or new work. Just don't listen to it if you do not like it.
