Rare photographs from Nirvana’s first concert in March 1987 have been unearthed and shared by an unlikely source: Maggie Poukkula, the 19-year-old daughter of Tony Poukkula, a member of Seattle band Laytem who grew up with Kurt Cobain and hosted the fledging outfit’s first show in his basement. Last week, Poukkula tweeted a photo strip featuring three snapshots from the 1987 gig in Raymond, Washington, along with the caption, “Pictures of my dad and Kurt Cobain playing together back in the day.” At the time, Nirvana’s lineup consisted of Cobain, bassist Krist Novoselic and drummer Aaron Burckhard, though that night, Poukkula reportedly joined the outfit on guitar for, at least, two Led Zeppelin covers.
