It might help to email the venue just to verify that they still pass along fan mail. It depends on the size of the venue. Let me preface this by saying I haven't received a response yet, but this was my methodology for my first band VV.

When The Killers played at The Orange Peel in NC, I tried emailing before I sent out my package, but didn't get a response so I sent it about 10 days before they were scheduled to perform. On the envelope I wrote the performance date in parentheses just as a reminder. After the show I emailed the venue again (to several different addresses this time!) To verify that my letter was passed along. A woman replied pretty quick & told me that yes, they gave it to their tour manager, which I think is common practice.

Like I said before, I haven't gotten anything back yet but I'm hoping its because they've been touring in Europe. I included a SASE, LOR, a picture as well as CD covers, with a note saying they didn't have to sign it all since I didn't want to look greedy. I didn't want to waste an opportunity either! Finally I included a sharpie as an extra incentive to sign right away.

Good luck, I hope this helps you!

So two of my all time favorite bands EVER are on tour right now and the dates are out and everything. If I were to send to one of the places that they were playing at would they be able to sign what I have for them and send it back? I've been DYING for their autographs since I started listening to them! Any help would be greatly appreciated

Also how many days in advance would you recommend sending to the arena? I've already checked if some of the arenas do forward fanmail and the following dates are close and the arenas do forward fanmail.
Band 1:
8/24, 8/27
Band 2:
8/29
