As far as LP material there was also the Castle of Glass/Kenji mashup.
Edit:
Until It Breaks, Waiting For The End/Hands Held High, High Voltage, and A Place For My Head were all incorporated in setlists as well.
I would guess not since the name Xero sounds extremely 90's. My guess if they discontinue Linkin Park would be to rebrand as the new Fort Minor or another name altogether. Honestly though I think they'll just remain as Linkin Park and maybe add a new lead vocalist.
Seeing the outpouring of love from every corner of the world has been heartwarming. I think Chester's friends and families can take solace in knowing that he touched the lives of so many people.
There are also bands that continued on with a new singer after theirs died like AC/DC and Alice In Chains. Whatever happens I'm sure the band will choose what's best for themselves, their families, and their fans - whatever that may be.
I don't want Chester's death to mean the end of Linkin Park but I can't imagine them with another singer. Going forward with Mike as the sole vocalist isn't realistic in my opinion. He just doesn't have the range that Chester does and his singing voice is more suitable to a complimentary role with the occasional lead vocal. Getting another singer wouldn't be the same but it would at least allow the band to continue. Chester is one of my favorite vocalists of all time and probably the most talented among bands that I actively listen to.
At any rate I hope we continue to get music from Mike and Brad if nothing else - whether that be LP, Fort Minor, or something else entirely. The band existed before Chester joined them but they never would have gotten this big without him. The moment that hooked me to Linkin Park was Chester screaming over the bridge of One Step Closer.
This is so hard to write about. I still can't believe he's gone....
I've been a Linkin Park fan since 2000. This is fucking terrible. The band means so much to me as an inspiration for my own musical work. This is crazy. I'm crying right now. My condolences to his friends and family.
