Switched On (also known as Switched On Stereolab or Switched On Volume 1) is a compilation of Stereolab's first three releases, and was originally released in 1992. The album's name is in tribute to Switched-On Bach and other similar titles from the late 1960s to 1970s that feature Moog synthesizers as the primary instrument.[3]Switched On was later licensed to Slumberland Records for a US release, and Rough Trade Germany, for that country, both in 1992.
