1.) Dr. Know is a punk band from Los Angeles, CA with roots in Ventura County, CA. One of the founders of the "nardcore" punk movement from Oxnard, CA. The band was started by Kyle Toucher, Ismael Hernandez, and Robin Cartwright in early 1981, and after auditioning a few singers, Brandon Cruz was chosen (although technically the first singer was a Ventura punk named Joey Pena). The band recorded studio versions of several early songs with Cruz, which led to television appearances and gigs on the Los Angeles circuit. In 1983 Cruz left the group, leaving Toucher to take over vocals just as the band was starting recording of Plug In Jesus for Mystic Records. Several more albums followed, including the Burn e.p. This Island Earth and Wreckage in Flesh were subsequently released on Death Records/Metal Blade, signalling a shift to a more Metal period in their sound. For This Island Earth the lineup was founding member Kyle Toucher on vocals and guitars, drummer Rik Heller and bassist Ismael Hernandez. Dr. Know broke up shortly after Wreckage In Flesh was released in 1989, although they did a few scattered shows up until 1991.

2.) Dr. Know is also the alias of Gary Miller, guitarist of the Rastafarian group Bad Brains.

3.) While to date only three releases have been made under this name, Dr. Know is also an alias of drum & bass producer Tom Withers, who is better known as Klute.
