Off the top of my head:

The Clash - Clash On Broadway, just because it covers a wide range of their stuff.
Anything else by the Clash - cos it covers the rest of their stuff.
Sex Pistols - Never Mind The Bollocks, cos it's a classic of its time.
Buzzc o c ks - Orgasm Addicts, simply a top class album.
Vibrators - Rip Up The City, soppy punk at its best!
Stiff Little Fingers - anything old by them just because they rock
One Way System - Return In Breizh, cos they're a shouty band.
GBH - anything by them cos theyre hard!
Anti Nowhere League - Live In Yugoslavia, awesome!
UK Subs - Huntington Beach, because they did some great tracks as well as a few dire ones.
Dead Kennedys - Give Me Convenience Or Give Me Death, reflective of the 80s.
Drop Kick Murphys - The Gang's All Here, cos they're close to old decent punk.
Destination Venus - Speak Up Brown, You're Mumbling, cos theyre a little known UK band who deserve to get more recognition.

Lol, some more...?
