At LA Weekly, Henry Rollins listed his top 20 punk albums:
The Clash – The Clash
Generation X – Generation X
The Adverts – Crossing the Red Sea
X-Ray Spex – Germ Free Adolescents
Sex Pistols – Never Mind the Bollocks
The Ramones – The Ramones
Eater – The Album
The Damned – Damned Damned Damned
The Fall – Hex Enduction Hour
The Buzzcocks – Another Music In A Different Kitchen
The Saints – (I’m) Stranded
UK Subs – Another Kind of Blues
Wire – Pink Flag
The Lurkers – Fulham Fallout
Alternative TV – The Image Has Cracked
The Ruts – The Crack
The Germs – GI
X – Los Angeles
The Minutemen – The Punchline
Stiff Little Fingers – Inflammable Material
I would swap out Alternative TV and add the Dead Kennedys. And Hüsker Dü and Richard Hell and the Voidoids deserve a spot, but otherwise this is a great list.
