I still think it's weird they try so hard to suppress all those HT anniversaries. Where they are now and their whole career is based on Hybrid Theory. it defines them. It's not like they didn't want to do it and try to forget about it now. It's not something they were kind of forced to do like Meteora.
I see so many bands celebrating album anniversaries, releasing anniversary editions with bonus tracks and what not, not even the label tries to do something like that, seem completely odd to me.
Even for the 10th anniversary it seemed like they strategically tried to avoid playing a show on that date.
You can tell me that everyone in the band is forgetting about this, they just don't want to for some reason. They even have staff and tons of other business people that should know that this is coming up.
On the other hand though with this event they are not afraid to celebrate MFR, which is at this point almost 11 years old by the way.
