Photographs from Nirvana’s first ever show have bee uncovered—and tweeted—unknowingly by a Seattle teenager. The photos, posted by 19 year-old Maggie Poukkula, were tweeted last week with the caption, “my dad and Kurt Cobain playing together back in the day.” Maggie’s father Tony Poukkula had known Cobain since childhood and would join Cobain, Krist Novoselic and Aaron Burckhard to play second guitar for covers of Led Zeppelin songs. The pictures are from the show he put on in his basement in Raymond, Washington in Spring 1987 that Maggie found inside her father’s books about Cobain and Nirvana.
