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. 
 
 "I had no idea that those were during Nirvana's first concert," Poukkula tells Rolling Stone. "My dad showed me them a while back, but he never mentioned that's what was going on in the photos. I found out because of all the articles. I didn't realize it was such a historical thing. I thought they were just cool pictures of my dad and Kurt jamming together." Poukkula said she found the photos tucked away inside her father's biographies of Cobain and Nirvana.

 According to an incomplete set list from the show, Nirvana jammed on covers of Led Zeppelin's "Heartbreaker" and "How Many More Times," but also performed nascent versions of "Aero Zeppelin," "Mexican Seafood," "Pen Cap Chew," "Hairspray Queen," "Spank Thru" and "If You Must." A recording of the band's "Heartbreaker" jam appeared on the 2004 box set, With the Lights Out, while a bootleg version of "If You Must" is available on YouTube. 
 
 Poukkula's shots come on the heels of a deluge of rare Cobain and Nirvana artifacts, many of which were incorporated into Brett Morgen's acclaimed documentary, Montage of Heck. Morgen was given unprecedented access to Cobain's archives, comprising mountains of notebooks and hours of never-before-heard audio cassette tapes, which featured eerie Beatles covers and the noise collage that gave the film its title. 
 
 After a successful stretch on the festival circuit, limited theatrical run and HBO premiere, Montage of Heck is set to return to movie theaters starting August 7th. ||||| Kurt Cobain has been studied and dissected obsessively in the years since his death in April 1994. Could there be anything left to learn about one of the greatest musicians of our time? The answer is yes, and it's in the new issue of Rolling Stone (on sale Friday), where Frances Bean Cobain speaks out for the first time about her father's legacy, life after his death, her stormy relationship with Courtney Love and the HBO documentary Kurt Cobain: Montage of Heck that brought them all back together again. Above, in an exclusive clip from the film — which airs May 4th on HBO and in select theaters on April 24th — the Nirvana leader strums and sings along to a beautiful, haunting melody that the film's director Brett Morgen tells us is a previously unheard Cobain original song that he discovered in Kurt's storage facility in 2013.

 "What really surprised me was watching my parents' love story," Frances, now 22 years old, says of the film, which started to come together in 2007 at Love's request. "Because they were so close to my age now. It was like friends falling in love — I did not expect that." 
 
 Frances welcomed Rolling Stone's David Fricke into her Los Angeles home, where she spoke for three hours about growing up in the shadow of a father she can't even remember. People are often stunned when they meet her and see the striking resemblance, an effect she calls the "K.C. jeebies." "They look at me," she explains, "and you can see they're looking at a fucking ghost." 
 
 Throughout Fricke's cover story, Frances speaks candidly about her father, who she refers to as "Kurt," and Morgen explains how she ultimately shaped the entire Montage project. "She said, 'For 20 years, my dad has been like Santa Claus, this mythical figure. People come up to me and say, "Your dad's so cool." And I don't know him. I want to present Kurt the man.'"

 Frances and her mother, Courtney Love, have had a volatile relationship over the years, though recently they've become close again. In our story, Fricke describes how before the film's premiere at the Sundance Film Festival, they watched Montage of Heck at a private screening room in Burbank, California. It was Love's first time seeing the documentary, and Frances sat in her lap to help her through the film. In a particularly devastating scene in Montage, a clearly intoxicated Cobain struggles to sit upright as his infant daughter sits in his lap getting a haircut. 
 
 "My mother held me, cried on me and just said, 'I'm so sorry, I'm so sorry, I'm so sorry," Frances tells us, recalling watching that scene with her mother. "Just kept saying it over and over. But then she said, 'Do you realize how much your father loved you?' And I said, 'Yeah, I do.'" Morgen remembers that Frances revealed more to him about that moment: "Frances said it was the first time her mom and apologized for anything relating to her youth."

– Most teens don't find music history in their dad's stuff, but Maggie Poukkula's dad is Seattle musician Tony Poukkula, who was a friend of Kurt Cobain. Her find? Photos of Nirvana's first concert, performed by then 20-year-old Cobain and his new band in March 1987 in Tony Poukkula's basement. "My dad showed me them awhile back, but he never mentioned that's what was going on in the photos," Maggie Poukkula, 19, tells Rolling Stone. "I found out because of all the articles. I didn't realize it was such a historical thing. I thought they were just cool pictures of my dad and Kurt jamming together." She tweeted the photos last week, and the post quickly went viral. That first concert featured the early Nirvana lineup of Cobain, bassist Krist Novoselic, and drummer Aaron Burckhard playing original songs and Led Zeppelin covers. Similar early-days footage of Cobain and Co. featured in the recent documentary Montage of Heck has renewed interest in the grunge band. The Emmy-nominated project includes home movies, never-before-heard music, and intimate interviews with Cobain's family and friends, notes SPIN. After being critically acclaimed at festivals across the country, the film will return to theaters on Aug. 7, adds Rolling Stone. (Want a little more Cobain history?
