Before Nirvana, Dave Grohl played rums in a band called Scream. But even before that, he was in a short-lived Washington D.C.-based band called Bain Dramage.

Looks odd to see him playing without the long hair.
Also, it sounds like they were playing a song called “In the Dark”.
That song was later recorded in a demo session at a studio called the Laundry Room in 1986. You can check out all of those songs by clicking this link.
