I went to lots, BITD... but my memory isn't what it used to be.
The Boneless Ones were fantastic, every time they played.
(reformed for 1 gig in Swansea last month - heard good reports).
(meaning: The gig involved skateboarding, broken instruments and loss of blood - same as it ever was)
Saw The Stupids at Mon's Ramp Jam in Banbury.
Probably the peak of the mid-80s UK skate-punk scene.
Fugazi (never saw them when they were Minor Threat) - always excellent and they tend NOT to attract the disruptive idiots to their gigs.
Never caught Black Flag, but have seen Rollins several times over the years (gigs and spoken word) and he's always good value. Thankfully, he doesn't seem to attract the disruptive idiots to his gigs anymore. Tho from reading "Get In The Van", Black Flag often spent their time scrapping with neo-nazi $h1theads who came to dusrupt their gigs.
Saw DKs a while ago. Putting aside my reservations about them touring without Jello
... they did an excellent live set; No rock star B.S.; Highly recommended.
Circle Jerks, JFA, Husker Du, Agent Orange.... Ooh, it takes me back.
