It looks like Rock in Gensokyo is like Coachella, except ALL the bands are good(Muse? Really?), the tickets aren't expensive as fuck(they're practically giving them away), you might still have the option of going one or two days(seriously, FUCK Muse), and it won't get so damn hot. It could have been held in an above ground Hell of Blazing Fires and you would never know the difference.
Also, You're now picturing Reimu and Her Annoying Friends playing Don't Play Easy. Manually.
