Yes, Public Service Broadcasting is the name for a band — composed of the corduroy-obsessed J. Willgoose and his drumming companion Wrigglesworth. The pioneering London entity samples from old public information films and sets them to contemporary music. Granted exclusive access to WWII-era archives from the British Film Institute, their propaganda-inspired music is an educational aural affair complete with krautrock guitars, banjo, atmospheric synths, piano and propulsive drums. Experience the spectacular PSB by streaming “Spitfire” — the lead track off their 2012 EP The War Room below.
