In that case, your statement has total validity. Perhaps it is just a different understanding of the word "Katatonic" that separates our statements. Of course it should go unstated that I agree that I also would not call ATG, Isis, Muse, etc a Katatonia-like band. I simply infer that these bands have also culled and awoken the most sensitive parts of my soul. In the end, and maybe I am oversimplifying here, it is the feeling that bands give you, regardless of the aesthetic or playing style. And as is the case with me, depression is my niche; thusly I created the list you read a few posts ago.
And sorry for being so verbose, but alcohol truly inspires the scribe within me
