Javelin is the creative endeavor of George Langford and Tom Van Buskirk, cousins from New England. Javelin began making music in 2005 under the auspice of the Providence, RI art/noise scene. They wielded a mobile boombox soundsystem that used FM transmission to pump out pop-influenced sample collages, and their aesthetic aimed for surrealist block party in-a-box.
