Just got the heads up about Rock Show, an interactive concert poster app for the Apple iPad. Using this app, you can browse and buy concert posters by Todd Slater, Strawberryluna, Iron Forge Press, Powerhouse Factories, and a few others. I’d be willing to bet that they will add a lot of new content in the coming months. I haven’t used it, so I can’t vouch for it, but it sure looks pretty cool. Check it out at RockShow.fm.
