The new Slash record isn't bad at all (it is a bit middling, but Slash is getting older), despite many critics not liking it.
I'm not entirely sure why that is, Dave Grohl is on it. Critics usually mindlessly eat up anything anyone-who-had-anything-to-do-with-Nirvana breathes on.
Oh, I get it, Grohl is only on one track, and that annoys them.
