Well that is shit. Here is my epic autograph story.
I followed NIN on tour last year, 4 stops in 9 days. @ Stop 3, the guitarist threw his water bottle into the pit - I grabbed it.
SB Bowl is a TINY ass venue so you have to walk past the tour buses to get to the venue. After show is over, we stick around the tour buses. We see the drummer get into 1 bus, so we know which one to camp out now. Fast forward 30 minutes or so, no one gets onto the bus except for one dude with a bike and a headset. We ask him if we can get it signed, he says "sorry but everyone is asleep".
So wtf are a buncha die hard fans gonna do? Ask him to get the band to sign the water bottle and we'll pick it up later. He actually says YES and gives us his number.
18 hours and 50 miles later, we meet up with him at the parking lot of Shoreline. Props if you can ID all the signatures. Triple props for identifying related acts.
