Can't believe somebody didn't think of doing this sooner. Oh wait, they did, back in 2009, and we just missed it somehow? Figures. Our bad. My Favorite Bands Festival is more or less what it sounds like: Your favorite bands all playing at the same bill. Well, except it's not your favorite bands, exactly (small detail). Rather its tribute versions of your favorite bands. To wit, this year's bill has acts paying tribute to Van Halen, the Flaming Lips, the Rolling Stones, Tom Petty and more. The whole thing costs ten bucks and it's taking place up in Greeley on Sunday, September 18. Visit the festival's website for more detailed info.
