Irish Metal and Rock…

What are your opinions on Irish Metal and Rock bands? Is there any particular ones that you would say stand out or that you would call some of your favourites? 
Is there any smaller, less known Irish bands that you listen to or have discovered at festivals etc? 
I’m asking because I’d like to hear the rest of the world’s views/opinions on our Metal/Rock scene and if it is indeed bigger/better known in other countries than it is here

What’s your thoughts on it then?
