I think I saw a YouTube vid a while back with some band at one of the squares playing Metallica (just Enter Sandman) and I think some 90s grunge. I recall the person filming mentioned the demographic changing. I'm 54 years old, only very part time for now. But I'd love some heavy rock bands now and then.
We may not dance, but we certainly don't mind spending money at the bar and rocking out at the stage. I figure it will be a few years before I hear any Slayer. But some 80s metal would be nice.
