Scott Rockenfield began playing drums at the age of 12. Influenced by bands such as Rush, Kiss, and Van Halen, Rockenfield is entirely self-taught, having never taken drum lessons. During high school, Rockenfield met Michael Wilton at the legendary Easy Street Records in Seattle, and the duo formed Cross+Fire, later adding Chris DeGarmo and eventually, Eddie Jackson.

The four-some changed its name to The Mob, and rehearsed continually in the basement and garage of Rockenfield's parents' house. In fact, as Queensr˙che began after adding Geoff Tate, much of the band's first four records were written there! Although not one of the primary songwriters in the band, Rockenfield is known for composing some of the moodier segues/songs, such as "9:28 a.m.," and "Electric Requiem." He does have some regular songwriting credits as well, with "Dis-con-nec-ted," and "Rhythm of Hope" being songs primarily composed by Rockenfield.

Out of all the members of Queensr˙che, Rockenfield (who is affectionately called "Scott Rock" by fans and his bandmates) is the most active musically outside of the band. In the early-1990s, he started composing music for TV commercials, eventually working his way into scoring videos and film. In fact, with his collaborater and friend Paul Speer, the duo was nominated for a Grammy Award in the "Best Longform Video" category for their project "Televoid" in 1998. The pair went on to record an instrumental CD entitled "Hell's Canyon" a few years later, which received good reviews.

In addition to Queensr˙che, Rockenfield is also a founding member of Slave to the System, a heavy rock band that also features Kelly Gray (ex-Queensryche, ex-Myth), Damon Johnson (Brother Cane, Whiskey Falls), and Roman Glick (Brother Cane, Jackyl). The group released one self-titled album in 2001 (independent release) and once signed to Spitfire Records in 2006, re-released it. The band toured all over the Southern region of the United States in Winter/Spring of 2006.

In addition to his musical outlets, Rockenfield is also a businessman, having created RockenWraps, a drum finishing company. Although it started out small in the mid-2000s, the company has done well. A number of well known drummers are using RockenWraps, including Shawn Drover of Megadeth, Vinnie Paul of Hell Yeah! and Pantera, Joey Jordison of Slipknot and Deen Castronovo of Journey.

Although free time is probably not a luxury Rockenfield enjoys these days, when he's not busy with music and his businesses, Rockenfield enjoys spending time with his family and photography.
