Black Flag has some great songs but I’ve never been a huge fan even though I feel like I should be. Dead Kennedys and Dropkick Murphy’s older stuff can’t go wrong though.
Johnny Thunders and the Heartbreakers Live at Max's Kansas City is also one of the all-time great live albums. I do love Dropkick Murphys and the Pogues, too. Elvis Costello, REM, and Television for adjacent stuff. Buzzcocks.
