I need more punk
 

Bad Religion, Black Flag, Pennywise, Dead Kennedies, Suicidal Tendencies, The Offspring, and Green Day (I consider them punk) are some of my most favorite punk bands, but can anyone tell me of some other bands, I would really like to expand my punk library.

I just got the Stooges - Fun house its amazing

Middle Class, The Ergs!, Descendents

Definitely Descendents.

Also try Lagwagon if you like Pennywise. Hot Water Music is another good one.

This for sure, as well as Minutemen, Husker Du and maybe the Meat Puppets as well. Although an older band, you'll probably love the Clash also as they're a major influence on what you already listen to. Finally, while Frank Zappa isn't a punk artist per se, his albums "Freak Out" and "We're Only In It For The Money" are most definitely punk in spirit.

The Damned - Machine Gun Etiquette
Johnny Thunders - LAMF
The Ruts - The Crack
999 - 999
Penetration - Moving Targets
