thomas, By the way: If you know #metal or #rock bands that you would like to have here in the metalhead.club or in the #Fediverse, just write to them and invite them to the metalhead.club!
Some #bands - especially the smaller ones - can simply be contacted via their homepage via e-mail. Or via other social media channels.
Admittedly, the likelihood of a band wanting to use another social media channel is understandably rather low for many. But maybe we can convince one or the other band!
