Is all slow and sad music Doom-Metal?
Once again the short answer is no! There is a lot of slow and sad or dark music in the world, even within pop music (Tori Amos being a good example). It would be an over-generalisation to call all sad, dark and slow music Doom-Metal. Besides the obvious fact that it needs to be metal there are also other music genres that are slow and mournful; Dark-metal, Dark-ambient, Dark-wave and Gothic-metal are amongst the best examples. These days there even is depressive rock – confusingly enough often produced by bands which were once Doom-Metal orientated. Anathema is a good example. By virtue of the fact it is in essence rock it cannot be considered a part of Doom-Metal.
