Radio 4 has been played on NTS shows including Rhythm Connection, with Sound Of The Underground (The DFA Remix) first played on 27 July 2017.

Radio 4 were a politically aware dance punk band, from New York, USA (formed 1999) & named after a Public Image Ltd. song. Though their music is often compared to releases from the likes of Gang Of Four, flirtation with electronics results in a more 21st century sound. The group had disbanded in 2012.
