Travis Barker is reacting to the death of his friend Adam "DJ AM" Goldstein.
The rock drummer tweeted on Saturday, "Don't know how I am gonna play 2night but I am for AM. My brother is gone. I love u and miss u, I'll never forget all the good times we had."
He went on to write, "I'll never forget everything we've been thru and every time I play the drums I'll think of you. U were an amazing friend/DJ/human being."
In closing, he tweeted, "Rest In Peace my brother, this really ****s me up."
Barker and Goldstein, who collaborated on music together, were the sole survivors of a 2008 plane crash that claimed four lives.
