Nearly four decades after the creation of punk rock, many of the genre's iconic stars are still going strong. Some continue rocking with the bands that first made them famous, while others are soldiering on with new groups or venturing into non-musical creative pursuits. How have your favorite punk rockers fared over the years? As you stroll (or scroll) through our Punk Icons Then and Now gallery, salute the worthy and gob on the has-beens -- then holler in the comments section if we forgot any key figures.

Now: The punk legends are on the comeback trail, but not with Rollins. Maybe the shirt-rocking spoken-word maven's too busy with his National Geographic show, 'Snake Underworld With Henry Rollins.'

Despite no longer leading the Kennedys, Jello continues to make records and rake muck. In 2000, he ran for president, but his 'Let's Lynch the Landlord' platform didn't play in the heartland.

Then: Television founder Richard Hell quit that band to rock with the Heartbreakers and help define the 'Blank Generation' with the Voivods before leaving music for good.

Now focused solely on the written word, Hell recently published the excellent memoir 'I Dreamed I Was a Very Clean Tramp.'

Then: The other H.R. -- not the muscle-bound Black Flag frontman but the singer for Bad Brains -- helped invent hardcore as we know it.

Bad Brains returned in 2012 with 'Into the Future.' Despite the forward-looking title, they're still mixing punk and dub like they did back in the day.
