Worst Concerts You Have Attended ??

This thread confirms there are so many reasons a live concert can go bad for reasons besides the actual performance being bad. I started attending rock conserts when I got my first car in 1971. Tickets were cheap, most were there to have a good time, were high and the music was almost secondary.  Once ticket prices went through the roof and all concerts were assigned seating with few(er) getting high, people went to actualy listen. Add to that the fact that most modern bands can't reproduce their studoo album sound in a live concert setting it's rare that any rock  concerts are worth going to.

The worst for me was a show that didn’t happen. Was going to see one of my favorite guitarists  Richard Lloyd from Television fame at a small club in Detroit. I won’t go into details but he got kicked out of the venue before the lead act was done. And then a few years later he was supposed to play a small bar in Detroit and I go there and he canceled that day. So disappointing. Richard if you’re out there get your s—- together. I’d say you owe me a show but I’ll never try to see you again. 

Led Zeppelin North American tour 1977. Waited for this show for months. We had seats just off the side of the stage where the band went up the steps to the stage. Bonham comes out, loud clapping, John Paul Jones, noise getting louder, Jimmy page is ready to go on the stage and the lights dim. Page has a guy on his left and one on his right. They basically carry Page to the stage and plug in his guitar. He's just standing there oblivious. Heroin does that to you. Robert Plant hits the stage and the band starts playing. Horrible mixing and sound. Bonham does a 20 minute drum solo. Zeppelin, the Hammer of the Gods. Not that night. 

The problem with nearly all concerts is the venue or the sound crew (or both) along with greed. Most agents will book their talent at the most profitable place regardless of the acoustics. Unfortunately some groups are just fine with that too but it causes otherwise loyal fans to disrespect.
Have heard Massey Hall Toronto is one of the best. Fraze Theater Dayton, Ohio (outdoor) is a gem. Rose Music Center worse than a wind tunnel.

Golden Rule: If you can't get primo seats don't go and the smaller the venue the better. Half the people at large concerts don't know who's playing and the other half are there to get drunk and throw up.

Took a girl to see Rod Stewart in the 80's. Rod was in his disco "Do ya think I'm Sexy" era. He appeared in a spandex outfit and spent most of the night displaying his ass to the crowd. 70's, my ears were damaged when seeing Marshall Tucker at a 1200 seat field house, playing at Yankee Stadium sound levels. Shame on that great band.

Did see a great Dylan (electric) concert in 70's but had decent seats. Diana Krall in second row was priceless. Van Morrison at Greek Theater UC Berkley one of my best ever. Steely Dan, Boz Scaggs, Bonnie Raitt, Lucinda Williams yes,yes, yes! Again, get really good seats or get a really fine stereo system.

P.S. Ringo Starr. No level of quality drum beat could ever make up for that awful voice. Left early.
