I don't care for them, but I do have a slightly funny story regarding how I came to first hear their music.
I spent more than a year deployed to Iraq, and during that time I ended up with a lot of down time where I was just waiting for something to happen. In my entire life up until that point, I had never owned more than a dozen music albums, but something about the combination of lack of anything to do, a large amount of income that was difficult to expend and the fact that Amazon will ship to a war zone meant that my music collection quickly skyrocketed.
During the waning days of my deployment, my job complete and passed on to the next poor sap, I was sitting in a tent playing Dawn of War on my laptop while listening to the Dropkick Murphys album "Blackout". One fellow in the tent struck up a conversation regarding my taste in music, and he seemed to appreciate the particular sounds of that Boston punk band. He suggested that I would probably also like Coheed and Cambria, because it was quite similar. He also noted that their latest album was on sale at the post exchange (the PX carried a handful of the most popular albums in the states).
Since I had been on something of a journey of musical discovery, and the guy at least seemed to share my tastes in music, I decided I would investigate his offer and picked up the album a few hours later.
As I listened to the opening tracks I grew increasingly distresssed. Not only did I not like the band, it shared no connection with the music style of the Dropkick Murphys. Unfortunately, I was never able to determine if it was some sort of cruel prank or just stupidity that lead to the suggestion, as the guy had already departed the tent for good by the time I found out just how badly I had been misdirected.
