I got into it finally; listen to it a couple more times?
I'm just gonna complement to what you said, it's my least fav. of all the albums, and i don't understand the buzz about it, yet it does still feel like NFG, although i feel like this was a very... easy? album to make. Definitely has its ups and downs.
i feel like Radiosurgery is a step backwards. in fact, i think it's a few steps backwards. and i like what you said: a very easy album. it doesn't feel like they put a lot of heart into it like with their other albums. it just feels very lazy, for NFG.
