More than 26 years ago, a young Nirvana performed an acoustic set at a pub in Edinburgh, Scotland.

Now, decades later, the Dec. 1, 1991, performance has appeared online. Nirvana performed the show at Edinburgh’s Southern Bar under the pseudonym “Teen Spirit” to an audience of just 20 people, according to Rolling Stone.

This was a different performance for Nirvana, as frontman Kurt Cobain played guitar during the set, and drummer Dave Grohl played bass.

Listen to some audio from the concert below, including the popular Nirvana tracks “Dumb” and “Polly.”

Nirvana’s landmark sophomore album, “Nevermind,” was released roughly two months prior to this show.
