An emo/pop punk band located in the San Fernando Valley (Southern California). The name derives from when a teenager (most likely male) is masturbating and gets walked in on to be caught in the act; hence knock first.
Changed their name to Down For The Count
in 2003 due to a conflict with the name of an ABC show also called "Knock First".
Drummer: Man this fucking sucks, we came up with the name first.
Lead Guitar: Yea, what a gyp.
