Chosen as a motto from words cut of a German newspaper for an exposition for young European artists and afterwards it was initialized as the name of the band. Knife Party — From the song "Knife Prty" by Deftones. The name caused consternation at first as it implied that they supported knife crime, although Rob Swire stated that "...we're not advocating any type of knife-related crime any more than Swedish House Mafia were advocating organised crime." Knuckle Puck — The band's name was inspired by a Stick to Your Guns t-shirt that said "Knuckle Puck Crew." Krewella — The band's name stems from member Jahan Yousaf's misspelling of the word "cruel" when she and her sister Yasmine began writing music, and is not a reference to Cruella de Vil. L The La's — The band was formed in Liverpool, and "la" is a well-known Scouse phrase meaning "lad" or "mate". Ladytron — From the song "Ladytron" by Roxy Music. La Roux — The band's name refers to singer Elly Jackson's red hair and tomboyish appearance, mingling the masculine ("le roux") and feminine ("la rousse") French terms; she has said: "To me, it means 'red-haired one'—and it does, vaguely. It's just a male version of 'red-haired one. Lasgo — From the Scottish city Glasgow with the first and last letters removed. Led Zeppelin — The band name "Led Zeppelin" refers to the Hindenburg disaster; and a joke made by Keith Moon and John Entwistle. The two were discussing the idea of forming a band with some prominent young guitarists at the time. Moon and Entwistle suggested that a supergroup containing themselves, Jimmy Page, and Jeff Beck would go down like a "lead balloon", a British idiom for disastrous results. They intentionally misspelled the name to ensure correct pronunciation by announcers. Letters to Cleo — The name refers to lead singer Kay Hanley's childhood pen pal Cleo. Level 42 — From the Hitchhikers Guide To The Galaxy series of books by Douglas Adams. Some confusion surrounded the name in early years outwith their home country of the UK when, bored of journalists asking the same question "What does the band name mean" over and over they started to give different daft answers to amuse themselves, amongst them being that they were named after the worlds highest multi story car park etc. Lights — Born Valerie Poxleitner, "Lights" stemmed as a shortened nickname
