I know i'll be showing poor taste in music, but I'll use Blink 182 as an example. Hey, I was 18.
The cheapest I ever saw a Blink show was for $8. Normally I'd pay anywhere between $8 and $12 to see em (yes, I've seen them a lot) Once Enema Of The State was released though it all went downhill. It was like everything I liked the band for was over. Blink was just this funny quirky pop punk band before making dick and fart jokes and shit and that was all good. Then they tried to go all serious and shit. See, if they just went serious (even though they had The Aquabats old drummer Travis AKA Baron Von Tito) that would be fine, but they tried to mix the two and it just sucked ass. Enema wasn't so bad, but all of a sudden ticket prices were through the roof so I washed my hands of them and haven't seen em since. I think the most I ever paid to see em was $15 and that was because they were on the Sno-Core tour with Primus, Long Beach Dub All-Stars and The Aquabats.
Enema wasn't a fluke either, they just got shittier and shittier untill they broke up. A horse that needed to die
