I get it. More than you realize.
I went and looked and you're right to an extent. Dillwaters who do no entertaining and don't add spectacle to their performances will change up the set lists some. They still play about the same number of songs, but they may play Oobla Fuckity Fuck first tonight and save it until third the next. I've seen enough to know that the stage patter, even when they claim it's just for you, is pretty generic no matter where they go.
That's your deal though. I don't want to go see some jeans-wearing bar bander who flies by the seat of his pants. I want to see a show that's been practiced, one that's rehearsed, one that has a flow to it. I want to be entertained.
I love The Eagles, but one of the worst concerts I've ever been to in my life was their Hell Freezes Over tour. They just sat there on stage on stools and sang. I didn't expect blood spitting or fire shitting, but come on. I can listen to a CD and save the $100 if all you're going to do is sit there like a stump.
That's the think Kaos, you think you get it but you don't. Sure, you may have a repeat of a song or 2 from concert to concert, but you are dead wrong on that they sound the same. Completely, dead, wrong. In your example, a song that they play 1st to open a show is going to sound and be done completely different that the same song done in the middle of there show or as their closer. I have seen it too many times dude. I am not trying to tell you shit about KISS that I have no fucking clue about...why are you trying to tell me about the concerts I have been to that you have no fucking clue about.
The same song may have completely different intros, middle jams, or endings depending on the feel of the show and where the song is played during the setlist. One of my favorite live songs for instance..."Two Step", by Dave Matthews...Dave sings a different intro, with completely different words every show. EVERY TIME. One time it may be 2 line intro, the other time it may be a 2 minute intro...but it is different every time. Does Dave "practice" this before hand. No clue. But I would bet that the band doesn't "rehearse" his intro everytime before he sings it. The band adapts to how he is singing and the energy he has for that intro. i have seen it happen dude.
Another time, I was at a Dave show in Atlanta and he had a guest guitarist come up on stage and play with him during a song called "Jimi Thing" where the guest guitarist, in the middle of a jam starting playing a pretty fucking cool guitar lick. Dave walked over to him, and watched him play it, and then started playing his guitar lick on the accoustical guitar. He continued to play this guitar lick, that he just learned, while the guest started playing lead on the electric. The band adapted to the new lick and rythem, and Dave even started singing lyrics based on this COMPLETELY improvised new sound to this song. I saw this shit with my own eyes. I even went back and downloaded a bootleg of this song to make sure that I heard what I thought I heard. That shit happened. Live in front of my face.
I have seen DVD's where the band is jamming and the drummer, who is a bad ass, does some new funky ass shit, Dave looks back at him and smiles and lips, "That's bad ass". I have seen this shit dude.
Again, I am not trying to tell you shit about KISS because I have no clue. Don't try and tell me about my shit because you have no fucking clue...
