Definition

A live musical performance stripped of electric instruments, typically featuring acoustic guitars, drums, and raw vocals. Popularized by MTV's concert series, it's the musical equivalent of showing up to a party without your carefully constructed persona.

Example Usage

The band's unplugged version of that song is way better than the studio recording.
