It's just a joke! Actually I do love death metal. See this as a free public service if you have no imagination for an awesome band name. Remember to check if the name is not already taken before adopting it.
I stole most of the pictures and inspiration from French webzine nihilistic-webzine-distro.fr. You'll get the band of the name in picture filename, go read their interviews and listen to their music!
It's clearly a copyright infringement, if it's actually problem, please send me an email.
I found the fonts on dafont.com.
If you're done, go back and generate more band names!
