music bomb

to break out into song in a public place that typically does not have music at an unexpected time (no posters, no facebook events. well orchestrated, executed and completely random)

similar to picture bombing, but with music

Example 1: "Dude, did you hear that Andy walked into a random biology lecture class with an electric guitar, a massive amp, and a microphone and started riffing Baba O'Riley by The Who?"

"No way! I would have loved to music bomb that class!"

Example 2: "Andy brought an old school boombox into the Student Union, belted "You Raise Me Up" by Josh Groban, and left. We have just received confirmation that was a music bomb."

"I wish Andy would have consulted me about that music bomb, I play a wicked saxophone."
