I didn't go to many concerts between 1988-1991 (law school) and then between 1991 and 2000 while the kids were little, and then maybe I went to a few a year from 2000-2006. So, I basically missed everything important. Catching up for that with the last 6 or 7 years, where I have probably gone to close to 400 shows.
Anyway:
Last year, I had a ticket for Idles, but logistics got complicated and I couldnt go.
I would have liked to see Tom Petty's last Baltimore show, but there was a miscommunication.
The Tibetan Freedom Concert at RFK thing & Radiohead at the Club.
That last Foo Fighters thing at the Club. I had ffigured out that it was a free foo show and meant to get a ticket when I was downtown that day to go to a show at BlackCat and just forgot to go to the club to get a ticket.
The Beck thing where he played Lincoln Theatre and was mostly acoustic?
That last DC The Hold Steady show at U Hall.
