These paintings (and one drawing) were locked in storage after Cobain's death. Courtney Love recently unveiled them for auction. They were painted in 1993, during the recording of Nirvana's last album In Utero, and at the height of Kurt's drug addiction.
Yesterday, Seattle's famous indie record label received a heartfelt letter from a Virginia Tech student asking if Nirvana, the legendary grunge band that split up in 1994, would be willing to appear in a pep rally video to be shown during Homecoming Week, alongside several other recording artists like Ying Yang Twins, Slightly Stoopid and "three famous NFL stars." According to Sub Pop's Tumblr blog post, the staff members did their best to accommodate by dressing up like Nirvana and recording a response video to be released in coming days.
