He has continued to work with rappers, releasing extended plays with Yelawolf, Asher Roth, and Nottz, as well as with Blink-182 and the Transplants.

In junior high, Barker learned to play the piano and briefly tried singing, joining the madrigals men and women's choir.

[7] Barker, who was "sleeping on [his] friend's couch" and still working as a trash man, only intended to fill in for a few days but ended up joining the band.

[10] After the October 1997 release of The Fury of the Aquabats!, the group toured nationwide with San Diego–based Blink-182, who had recently completed their second album Dude Ranch.

Barker, who did not have time to prepare or practice with the duo, learned the drum tracks for the 20-song setlist in only 45 minutes before the first show and performed them flawlessly thereafter.

Barker's first album with Blink—Enema of the State—was released in June 1999 and catapulted the trio to stardom, becoming the biggest pop punk band of the era.

[18] Blink-182's next effort, Take Off Your Pants and Jacket (2001), was greeted with immediate success, debuting at number one on the Billboard 200 and going triple platinum within three weeks (the record eventually sold in excess of 14 million copies worldwide).

[27] Following a cancelled European tour, DeLonge went back to San Diego to record an album he deemed an experiment in ideas he felt weren't suited to Blink-182.

[15][28] DeLonge, not wanting to pay for a studio drummer, simply asked Barker to step in and perform on the record, called Box Car Racer.

Through a connection with Jerry Finn, Rancid vocalist Tim Armstrong contacted Barker in the summer of 2002 to record tracks for a rap/rock collaboration called the Transplants.

[31] He also began appearing in music videos, including Puff Daddy's "Bad Boy for Life", as well as adding to his collection of vintage Cadillacs.

[33] Shortly before the album's completion, Barker's girlfriend, ex-Miss USA Shanna Moakler, gave birth to their son, Landon Asher, in October 2003.

[34] LaSalle was named after Barker's favorite Cadillac, and the label was designed to branch out to find all types of music, be it country or hip-hop.

[35] Barker's doctor informed him that not only did he break his foot, but he tore tendons and ligaments—described by Hoppus as "the type of injury that people get in motorcycle accidents.

"[36] In the meantime, Barker purchased a Wahoo's Fish Taco franchise in Norco, California, and began work on a new Transplants record.

According to Barker, he was trying to blot out the guilt of giving his children a broken home, and consumed "excessive amounts" of prescription painkillers, marijuana and alcohol.

[46] He kept busy drumming for Idiot Pilot ("Elephant") and the Federation ("Black Roses"), as well as creating well-received remixes of Rihanna's "Umbrella" and "Crank That (Soulja Boy)".

[47] After a stint on the Honda Civic Tour with Fall Out Boy and Cobra Starship, +44 began work on a second studio album that October.

[55] The plane crash led Barker to make some lifestyle changes; he began running and swimming each day, and went vegan since leaving the hospital, although he had already been vegetarian for 17 years.

[51] After more than two years of setbacks and delays, Barker finally released his long-in-the-works solo debut, Give the Drummer Some, in March 2011.

[66] He appeared in the 2016 Grammy-nominated documentary film about American DJ and producer Steve Aoki, titled I'll Sleep When I'm Dead.

[68] In 2019, Barker teamed up with popular New Orleans alternative hip hop duo $uicideboy$ to announce Live Fast Die Whenever, a collaborative EP.

On April 24, 2020, during the COVID-19 pandemic, Barker was featured as the drummer during Post Malone's well-received Nirvana tribute show and fundraiser for the WHO COVID-19 Solidarity Response Fund.

On September 19, 2008, TRV$DJAM performed at a free T-Mobile event in Five Points with Jane's Addiction singer Perry Farrell and Gavin DeGraw in Columbia, South Carolina.

Barker also developed post-traumatic stress disorder, made worse by the intense guilt he felt knowing Still was not supposed to be on the plane.

[88] He stopped his vegetarian diet and began eating meat to increase his protein intake and possibly speed up healing of his burns.

"[90] Barker sued the plane's owners, Goodyear Tire and Rubber Co., and an airplane maintenance company that month; the case was settled out of court in December 2009 and the terms of the settlement are confidential.

In 2003, he appeared in an episode of MTV's Punk'd, a Candid Camera-esque television show, in which he took part in a set-up bareknuckle boxing match; he also appeared and spoke alongside Linkin Park vocalist Chester Bennington on MTV's Icon show honoring heavy metal band Metallica in May of that year.

[116] In a slight departure from his usual genres, he made an appearance on the 41st annual CMA Awards in 2006, performing a medley of songs by country icon Buck Owens with a group of artists including Dwight Yoakam, ZZ Top guitarist Billy Gibbons, and former Byrds bass player Chris Hillman.
