Carrion attended Mira Costa High School in Manhattan Beach, California with Descendents drummer Bill Stevenson and singer Milo Aukerman. He played bass guitar in the punk rock bands Con 800 and Anti, with whom he recorded demos. In 1985 he joined the Descendents, replacing original bassist Tony Lombardo, and accompanied the band on their first tour: "I get this weird note on my door, and it's like 'Hey, this is Bill. I'm thinking about doing the Descendents again. Tony can't do it, so I want to know if you want to give it a swing.' So we practiced getting me brought up to speed and then, right as school was ready to stop, Milo jumped in the van and we started doing shows." He later recalled of the experience:
That first tour was probably one of the most difficult tours and the funnest tour at the same time. The hard part was we were traveling in this horrible, horrible, beat-up '71 Ford Econoline van in the dead of summer with no air conditioning. You're laying on this plywood loft and the sun's sweltering on the ceiling. You stay at sketchy houses in sketchy neighborhoods with sketchy people. There's a show on Friday and Saturday, and then you're just wandering the states wondering what to do. "Holy smokes, there’s a show in Seattle and we're in El Paso. How many days do we have to get there? Nine. What are we gonna do for nine days?" Funny, crazy, and everybody was kind of dedicated to having about as much fun as could happen in a 24-hour period.
On the band's return to Los Angeles, Carrion lived with them in their rehearsal space, a storefront in Lomita, California. He performed on their 1986 album Enjoy!, for which he co-wrote seven songs. He left the band in the fall of that year: "I just wanted to keep kind of experimenting, and that's really it. It was like 'Okay, cool, you're taking the ship north, I'm going south. Roger! He joined the punk rock band Doggy Style, his first collaboration with Brad "Daddy X" Xavier, playing on their 1986 album The Last Laugh. In March 1987 he moved to Washington, D.C. to join Dag Nasty, performing on the albums Wig Out at Denko's and Field Day and the EPs All Ages Show and Trouble Is.
