My university had a week-long music festival, showcasing all the talent at the university. I played guitar along with some of my gameboy and nes tunes, and a friend accompanied me on drums. Here's a link to the 20minute set. It was fairly well-received! I thought it was either going to be too loud for everyone, or people would just leave, haha. All the tunes are pretty much in a rock/metal style.

Ps: I was sure to give full credit to the creators of the visuals, as well as the band who had used them. Anamanaguchi's Dawn Metropolis album.
