System Of A Down’s Shavo Odadjian shared photos with members of Linkin Park and Frank Zummo, with a heartfelt caption paying tribute to Bennington.

Yesterday, Blink-182’s Matt Skiba shared an Instagram video learning Linkin Park's “What I've Done” (perhaps transposed in a different key) with his guitar technician helping out.

Linkin Park first announced the tribute show back in September—it will be the first time the band have performed since Bennington's unexpected death in July, after canceling their scheduled U.S. tour and Japan appearances.
