Can you tell me the name of these two bands?

I'm not sure about the genres because I really don't pay much attention to them so don't get pissed if I get it wrong but the first one I think was melodic death metal and the song that I heard had the word 'Monochromatic' in the title I think it was 'Monochromatic Stain' but I'm not sure. The second band had an album called Covenant and I remember that every album title they released was in alphabetical order.
