Hi Moony. Big day tomorrow
Babymetal put on a good show, well choreographed dancing etc, very high energy. And they've got legions of fans that know all the cues for massive audience participation. They probably aren't good musos themselves, but doesn't matter their backing musicians are always the best.
I like Bandmaid too, they're very professional. Their product is very polished, even their acoustic stuff is a pleasure to watch and listen to. And of course it's always good to have a gimmick
Speaking of backing musicians....the drummer deserves a payrise.
