By the time it had crystallized into its final three-man lineup, Nirvana had absorbed the full spectrum of upstart rock: the Minneapolis sound of the Replacements and Hüsker Dü, the Boston post-punk Pixies' surf pop, Bad Brains' D.C. hardcore and so on.
But the influenced would become the influential: Sometime during the one-term George H.W. Bush presidency, Nirvana's relatively small discography would be refracted into a legacy that continues today. Six years after his death, Rolling Stone named Cobain its Artist of the Decade.
Scientology's theater of the surreal: HBO documentary 'Going Clear' puts the church's practices under a microscope.
Why would these seemingly thoughtful, intelligent people sign a billion-year contract to work for pennies a day? Why would these clear-eyed Americans cut off their families, divorce their spouses and leave their children based on the work of a science fiction novelist?
Read MoreWhen mob mentality tramples justice: 'The Central Park Five' revisits the case of teens wrongly convicted of a high-profile assault.

Rise of an entertainment titan: PBS' 'American Masters' highlights David Geffen's influence but only hints at a dark side.
David Geffen has made so many people rich and famous that everyone from Tom Hanks to Joni Mitchell lines up to sit on a couch and talk about his roller-coaster career in music, movies and theater. If there are pop culture consumers out there who have never heard of Geffen, they should recognize the Eagles, "Saving Private Ryan" and "Cats."
