I know people hate to hear us older guys use the whole "back in the day" routine......
BUT..."Back in the day" you wouldn't walk out of a show without 4 to 5 flyers in hand. You would see these flyers at EVERY bookstore, coffee shop, bar, record store, tattoo parlor, etc in the city of a show and every surrounding suburb. There was never a reason to say, "Oh, I didn't know about that show"
The internet is an AMAZING tool, though I think it has unfortunately led to a lot of laziness on the part of promoters and bands
(And once again, I am not speaking about any one band / fest in particular, even though I am posting on the KC fest thread).
