And maybe someone has already have it and shared it there.
Considering there are a lot of musicians and composers there, why not making a cooperation song ?
Here is another version : Considering that there are too much musicians for including all the ones that could be interested in this project, why not making a compo between groups of musicians ?
Ex: Group 1 (H, Radiczor, Alix) VS Group 2 (Blue Devil, Mashed, Ant.. wait wasn't it LionNinja before Ant ?... Nevermind)
No restriction for the genre (I suppose it'll surely be metal or something close to, considering this place

).
The groups's formation would be made the most randomly as possible.
This is just an alpha version of this idea, so it can evolve, if anyone has suggestions.
(I hope anyone would be interested

)
