Yeah, I may have cheated a bit with John Mellencamp. I'm surprised that I haven't seen Yes or ZZ Top yet. XTC played in my hometown with The Police once when I was 12. Had it been a few years later I might have caught that.

Buckethead (4 or 5 times)
Down
Metallica
The Sword

I'm not a concert going person, the bottom 3 were all the same show and The Sword was my favorite band at the time so a chance to see them open for Metallica was enough to get me out of my comfort zone.
Buckethead shows are a religious experience for me so I go see his show any time he comes to New Orleans.

Didn't notice it was supposed to be one per letter. Sorry.

No one told me the rules.

This is a good idea for a thread.

I don't care how it's done on Twitter. I'll write what I like! I'm a loner, Dottie. A rebel!

I'll post some all of the concerts I remember, even though I don't remember them all, some are likely local or regional enough people don't really know them, and/or some were at music festivals or openers for the headliners but I'll count them anyway. I'm also organizing this with last names for the letters, as that's how I try to organize my music database at home. I'll even put up the concerts I'm not super proud that I went to, including all those 90s Christian rock bands that aren't my cup of tea today!

A Audio Adrenaline
B Beck, Frank Black, Better Than Ezra, The Bloodhound Gang
C Citizen Cope, Cracker
D DC Talk
E
F Ben Folds (2), Fountains of Wayne, Furside, Nelly Furtado (2)
G Gear Daddies, The Goo Goo Dolls, Grand Buffet

Josh-da-man

I had to go through my old concert tickets to make my list.

It's actually quite surprising how many acts I've seen that start with either the letter "M" or "S."

To compile the list, I went with either heaviest, most interesting, or most out-of-my-circle act. So I went with Ice T over Iron Maiden for I, and Hank III over Hatebreed for H.

R could have easily been Rush or Rolling Stones, but I went with Rush. And F could have been Foo Fighters, but I went with Forbidden because I forgot I had seem them until I saw my old ticket (they opened up for Death Angel on their "Act III" tour, which was a really great show and brought back some memories).

Toby Dramit

Same for me, as well. I could have included Dire Straits, Supertramp, Buddy Guy, Rodriguez, Sting, Neko Case, and Gordon Lightfoot instead, to name a few.

PerryD

K - Kamelot, Korpliklaani, Kreator
L - probably will see Loudness in May
M - Manegarm, Melechesh
N - Nightmare, Nightwish, Nothgard, Nuclear
O - Obscura, Oceans of Slumber
P - band called Persefone is opening for Ne Obliviscaris this fall
Q - might see Queensryche at the end of the month
R - Rotting Christ
S - Sight of Emptiness, Sirenia, Skiltron

Some of the letters I could put down 10+ artists, easily...

cultshock

Yeahhh!!!!!

I didn't know we could count them as they aren't really a "band". I saw them twice, once opening for Nine Inch Nails and once at a local university (that show was crazy, they came right out into the audience, it was a smallish auditorium and did some acts that probably would have gotten them arrested for indecency at the arena NIN show ).

Can I count seeing Paul Stanley performing in Phantom of the Opera? That was pretty cool.
