Sicko is an American rock group from Seattle, Washington, formed in 1991. Exceptionally, the three-piece pop punk group has maintained a constant membership for every recording as a band. This line-up is Denny Bartlett (guitar, bass, vocals), Ean Hernandez (guitar, bass, vocals), and Josh Rubin (drums, brother of Aaron Rubin from The Mr. T Experience). Sicko released four full-length albums and five 7" eps as well as a retrospective CD with unreleased and rare material, a released demo and a tour video. They also appeared on approximately fourteen compilations on labels such as Lookout! Records and Liberation Records. They once exchanged covers with Cub. The vast majority of their recorded output was recorded by Kurt Bloch of The Fastbacks and released on Seattle-based punk label eMpTy Records. During its heyday - roughly 1993 to 1998 - Sicko actively played in numerous clubs throughout the Seattle area, and toured the United States, Spain, and Japan. A typical Sicko set would last about twenty songs lasting about 45–50 minutes, in a blistering, no-interruptions manner reminiscent of the Ramones or The Fastbacks (whose lo-fi style resembled Sicko, possibly in part due to Kurt Bloch's production input in the studio). Denny and Ean would typically switch places on the bass and guitar duties halfway through the set (and often handing each other their instruments while on stage).
