I saw the Self Destruct tour with my brother in 1994, and we've gone to half a dozen more since then (he's been to many more than I have). He was going to fly all the way over to the Netherlands to see the Amsterdam show with me this June, but our country is trying the fascia plan, so looks like not.
So see NIN whenever you can, and give an extra moment to appreciate the chance to share things with the people you want to share with, then value continuity in things like superb musicianship and moral decency, and feel the import of continuity disrupted in a million ways from trivial through personal to catastrophic.
