2008's The Dream found In This Moment moving in a rock direction. Brink did a lot of melodic singing with only a little screaming, and the songs were very accessible.
2010's A Star Crossed Wasteland saw the return of some of the intensity of their first album, but with plenty of melodic singing and catchy hooks. In This Moment has been on some very high profile tours, including Ozzfest, Warped and Mayhem.
I've interviewed Brink a couple of times, and asked her about the difference between U.S. and European fans:
"Europe has great crowds, too. They have a great time. I definitely noticed a difference with the pit. They don’t really beat each other up there and try to punch each other in the face. They usually do circle pits and just push each other, versus the U.S. where you see more people just destroying each other in the pit. In Europe they are having more of a good time and doing circle pits. In the United States they are beating each other up more."
