Kurt Cobain, 27 Years Old
The Nirvana frontman changed the world of grunge rock. He plowed through the Seattle music scene and his influence over the genre remains relevant to this day. The band's critically acclaimed sophomore release, "Nevermind," has been a revered classic album. He was involved in a tumultuous marriage with Courtney Love at the time of his death, and the two have a daughter, Francis Bean Cobain. His death was ruled as a suicide, though there have been several open theories about whether or not that's true.
