Either Rubin or Freese may have recorded the B-Side, 'Every Song', which comes from the album sessions. The drummer on the demos for this period are unclear with all tracks, depending on the time the demos were made, potentially being recorded by either former drummer Mike Chiplin, frontman Ian Watkins (who occasionally plays drums in demos) or Rubin. Then, after Rubin joined, he played the remaining two tracks on Liberation Transmission: 'For All These Times Son, For All These Times' and 'Everybody's Screaming!!!'. Before finding Rubin, Lostprophets hired session drummer Josh Freese to record the tracks on Liberation Transmission. He replaced Mike Chiplin, founding member and original drummer, who left the band in 2005 to pursue other musical opportunities. Rubin was the drummer for the Welsh band Lostprophets (although he is American). Rubin (right) performing with Lostprophets at the Leeds Festival 2007. Denver Harbor was dropped from their label one year after their only full-length album, Scenic, was released in 2004 but not before the band did a few round-trip tours of the United States and one week in Japan with a re-united Fenix TX. Immediately prior to working with Lostprophets, Rubin was the drummer for the band Denver Harbor, which included his older brother, Aaron, as bassist, who had played guitar in F.o.N., as well as 2 ex-members of the punk band Fenix TX. He has taken lessons from Blink-182's drummer Travis Barker and The Hooters' drummer David Uosikkinen. The winner of the 18-and-over category came from Argentina, and both drummers were invited to perform at the 2000 Modern Drummer Festival, by which time Rubin had turned 12. performance, which was picked by the magazine as the winning entry in its 'Best Undiscovered Drummer Under the Age of 18' contest.

Shortly thereafter, Rubin submitted a video to Modern Drummer Magazine of him doing a solo during an F.o.N. opened Woodstock '99 on the Emerging Artist Stage as a result, 11-year-old Rubin gained entry into the Guinness Book of World Records as the youngest musician to ever play on a Woodstock stage. By age nine, he was ready to play for F.o.N., a band that eventually would do three stints on the Vans Warped Tour, where Rubin would also fill in on drums for bands such as NOFX. After three months of 'toying' with the kit, he had taught himself to play and was jamming with his older brothers. He began playing drums at the age of eight, when he discovered his father's 1968 Silver Sparkle Ludwig drum kit set up in the garage.

Rubin was raised in San Diego, California.
