Hellist D.E. are the world's first "Brown Metal" band. It's actually a spoof cover band a la Spinal Tap, but with more of a leaning towards the death metal genre. The mark itself is based on the Limepickle clothing brand mark, but with some satanic leanings. The name was derived from a line in Metallica's Disposable Heroes (or was it?). The D.E. stands for "Dead Evil" (or does it?). The interesting thing about working on imaginary projects is making them look as real as possible. Think about how movies within movies never actually look credible, or how brands derived for movies look like student projects (read up about the brand developed for Steven Soderburgh's Side Effects by Pentagram to counter this).
