Drummer master Travis Barker of blink-182 fame shared this pic with a heartwarming message to DJ AM (aka Adam Goldstein) on Instagram early this morning (August 29).

His message reads, "Been 6 years, not a day goes by I don't miss my homie, my mentor, one of my favorite people to who have ever rocked the stage with and somebody who made me a better person. We went thru so much together ... The highest of highs and the lowest of lows....you were one in a million. Rest in power Adam I love you, till we rock again.... #DjAMFOREVER #GOAT ? from #PureNightclubLasVegas #DJAM"

Both Barker and AM were the only survivors of a horrific plane crash in 2008 that killed four people, two of which were Barker's assistant and security guard.

Travis Barker and DJ AM in May 2009, a little over three months before AM's death.

AM died August 28, 2009 in his NYC apartment. According to People.com, the medical examiner deemed AM's death as an accidental overdose.

About a month before his death, AM told MTV News, "Part of me feels like, 'Who am I?' I’m a DJ. This is my one chance. I owe it as a human who’s sober to say something to them. So that's my job. That's what I'm there for.” He was describing why he wanted to do the MTV show "Gone Too Far," a substance-abuse intervention TV show.

The duo were the official house band at the 2008 MTV Video Music Awards, and they straight-up slayed.

Barker's book "Can I Say: Living Large, Cheating Death, and Drums, Drums, Drums" debuts this October, and will undoubtedly include his first person POV of the plane crash and his friendship with AM. He shared on Saturday (August 28) that he'd officially finished his book and spent over a year on it, spending "as much time on this as [he] would an album."

We look forward to your book, Travis, and DJ AM, you are sorely missed.
