I don't listen to metal. So, I don't know if there's a call for 1 minute pieces. It sounds great. It just needs a song written around it.
I will say, about many of the metal pieces I've heard on this site, they seem formulatic. Are they like that in the produced/released side of metal? I only listen to the originals like Sabbath. All their songs song very individualistic. You won't mistake Iron Man with Sabbath Bloody Sabbath. Hey, I'm old.
