HOLLYWOOD, Calif. — Travis Barker says he lost a brother when DJ AM was found dead Friday inside a New York City apartment.

"Don't know how I am gonna play 2night but I am for AM," the Blink-182 drummer posted on Twitter Saturday just prior to his band taking the stage in Hartford, Conn. "My brother is gone. I love u and miss u, I'll never forget all the good times we had."

The close friends were the lone survivors in a South Carolina plane crash last September that killed four people.

"I'll never forget everything we've been through and every time I play the drums, I'll think of you," Tweeted Barker. "U were an amazing friend/DJ/human being."

"Rest in peace, my brother," added the 33-year-old musician. "This really f***s me up."
