I am a lover of progressive metal, and tend to make it often since recently.

I don't always want to spend 10 hours on a song that only lasts 9 minutes, and I like to see what you guys can do with the OS instruments.



Here are some examples of progressive metal.

PLEASE GUYS, I DON'T WANT TO BE THE ONLY ONE!!!
