Dum Dum Girls is an American rock band, formed in 2008. It began as the bedroom recording project of singer and songwriter Dee Dee (née Kristin Welchez)). She is currently based in New York City. The name is a double homage to The Vaselines' album Dum Dum and the Iggy Pop song "Dum Dum Boys". Many people believe Dee Dee's stage name was inspired by Dee Dee Ramone but she has stated that this is not true; it was her mother's name, which she took as her middle name after her death. The last name "Penny" was erroneously provided by British music magazine NME.
Dum Dum Girls remains Dee Dee's main musical output, with all songs written by her and recorded in collaboration with her producers.
