Malcolmb, this is a terrific song, one to be proud of. I'm not in the loop about Miriam, but real or not, she sounds like Dolores O'riordan which makes this sound like the Cranberries. I think I've told you that before. Regardless, this is an epic song. I like this mix, and I'm going back to listen again.
Ok, I just got back and I get it about Miriam now. It's pretty amazing that you can even have a virtual singer. As for the drums, I like them at this volume. It's not uncommon for Celtic music to be percussion driven, and since the drums don't really cover up anything, I say let them ride. Again, very well done, Malcolmb.
