Less than 15 off my list was in the last 11 years.
 
Most were between 1968 and 2001.
 
I saw almost no one live in 2002, 2003 or 2004.

Went to watch Exiter rehearse in a Hollywood warehouse- say who? - George Lynch & Mick Brown, a bass player and singer named Greg that never transferred to Dokken.
 
Played on the same bill as Juliette (FWIW)
 
I think that's it.

And by far the best show I ever saw    Pink Floyd
 
And at least eleventeen bar bands.

Everyday I see a plethora of live people, but I have no idea who most of them are.
The only one I can be sure of is myself
Then there's my family
My friends
My workmates
And a few I wish I'd never see live

Very interesting to see these posts - I've actually saved every ticket from every show I've seen.  I'll have to dig them out to look through them.  Just last Sunday I saw Dream Theater - great show.

Yeah.

When I was young I was that one weird guy (yeah I know) who didn't go to many concerts but instead bought the albums.  A few live experiences were good, but I don't really remember much of anything from them!  At least with the albums (some of which later were rebought as CD's and even later sucked into my computer where I still listen to them), they would last...
 
Here's a partial list (some were not of my choosing and I definitely don't remember them all!):
 
Bachman Turner Overdrive (at Knott's Berry Farm)
KISS
Van Halen
Kings X (opening for someone I can't remember, Guns and Roses maybe?  I think it was at Whiskey A-Go-Go.)
The Knack (intimate setting, we sat at the front table with the lead guitarist's Mom who had never missed a concert!)
Oingo Boingo (including getting front row seats from Danny Elfman himself for their famous Halloween show - we sat next to his wife and kid)
Jefferson Starship (in San Diego Stadium)
White Wizzard (new guitarist was business partner's nephew - he's VERY good!)
Rolling Stones (in San Diego Stadium)
Blue Oyster Cult (who our band, Foolish Pleasure, opened for in '84 - they were billed as Soft White Underbelly)
Walter Trout (many times, mostly in his tiny home bar called Perks right by the Huntington Beach pier)
Information Society (at an underground club called the Blue Room)
Sisters Of Mercy (at an underground club called the Blue Room)
Striper (at Knott's Berry Farm - bleh.)
Robin Ford
Jorma Kaukonen (of Jefferson Airplane fame)
Scorpions (friend bought seats but didn't know where they were, I bring binoculars.  Seats are dead center, first row above the "pit" - binoculars definitely NOT needed!).
 
Dozens upon dozens of bar original and cover bands.  Many with friends in the bands and even a couple where I got to go up and join 'em for a song.
 
I almost saw the Beatle's last U.S. show, but my parents thought I was too young to take along so they didn't go.  I also almost saw the Who, but the day before I was supposed to go was when Entwhistle passed away so the show was cancelled.  I KNOW I've been to other concerts, but I'm just not remembering them at the moment!  LOL.
 
There's also a very LONG list of bands I wish I had gone to see.  Oh well.

Rush
McCartney
ZZ Top
Elton John
Sting
Sheryl Crow
Tim McGraw
Eric Church
Point of Grace
Far From Home
Kenny Chesney
Van Halen
Scorpions
Dokken
Metallica
Kingdom Come
Amy Grant/ Michael W Smith
 
I also worked the Superpages Concerts for about 3 years as fundraisers for the Ice Hockey Team.  I heard a lot of concerts during those 3 Summers while working them.  Sometimes I would sit and watch for a while if it was a band I was interested in.  
 
My company used to set up AV and stages for events as well.  I think I really enjoyed watching many of the preshow rehearsals more than the actual shows.  Interesting stuff what goes on prior to the actual event.
 
My only regret is that I never got to see Lennon live, nor Clapton.  I had my chances on Clapton, but they just didn't happen.  It may never, now that he has scaled back.  I would have like to see BB King as well.
