In addition to the written announcement, the post includes a short video filmed at a band rehearsal showing Linkin Park performing "Castle Of Glass" with Nancy Wilson providing additional acoustic guitar and vocals.

The Filharmonic said that they rehearsed with LP as well so they're probably going to do a song with them to. I don't know how well a boy band performing with LP will turn out though. http://instagram.com/p/i5O_xHquVw/
