As always, I'd much rather see one band at a time. If more than one band is playing one night the chance of me being a fan (or close to) of both is like 10%. Waste of my time. Periphery is ok, but nothing that I would put on by myself every day. First part of the concert will probably be quite meh, as usual. I've seen only one booking with artists that I though were great on the same evening, The Four Tops and The Temptations. Both old Motown groups, so they couldn't miss. Within metal the difference between bands is often pretty huge, and I only like a very small percentage.
