This is rather brilliant! YouTube user bd594 describes his inspiration below:

This is dedicated to all fans of The B-52’s who are also known as the “Worlds Greatest Party Band”. This idea has been simmering in my mind for the last couple of years and after many months of procrastinating it is finally complete. I was also motivated to finish my robot band after seeing a YouTube Video from “The Trons” from New Zealand.

The Bit-52’s consist of:

Fred’s Vocals - TI99/4a computer, speech synthesizer and terminal emulator ii module
Kate and Cindy’s Vocals - Two HP Scanjet 3C scanners, UBunto and sjetplay written by NuGanjaTron
The Guitar, Keyboard, Cow Bell, Cymbal and Tambourine are all controlled by various types of push/pull solenoinds for a total of 23. The Solenoids are powered by four ULN2803 darlington drivers and everything is controlled by two PIC16F84A microcontrollers
