I know it's nothing new as a concept but it seems like in the UK there's been a major surge in tribute act festivals. Seems like an awesome cheap way to see some bands that you can't see anymore or have to sell your belongings to get a ticket.
I've been to a few over the last year or so and I'm loving them more and more. Went to a heavy metal one this past weekend. Amazing acts for 15 pounds.
Thoughts?
