That sort of music isn't my cup of tea. It's the younger gens that seem to get off on it, still...no surprise there.
They sound tight, that guy (assuming guy from the background vocals on the 2nd track) on the double kick must be interesting to watch. I had a double kicker on my drum kit, it was pretty cool though I on the other hand...
Good on 'em Bill, they have got a bit of a break and put some music down and that's brilliant.
I hope they are well received by their peers and I wish them and your Son great success!!
