The Light and Music entertainment platform Lightupyourbanjo began in 2010 when “Cash-a-billy with a Bluegrass bite” band Ed and the Fretmen wanted to have better lights on their banjo. They developed banjo lights with addressable LEDs for in and outside mounting showing interactive animations, written in C++ supporting the songs, and wrote songs to support the lights. In 2025 the Lightupyourbanjo bands will be fighting the darkness with the new O4 model build into their 3 banjos.
