Excellent stuff. Although I discovered him through Brand New back when Split the Country, Split the Streets came out, I think he is slowly surpassing them on my top artists list. BTC&C is everything I could hope for.
Regarding KD vs Brand New, it's pretty evident:
> any of KD's albums
KD's discography > BN's discography
KD's 10 best songs > BN's 10 best songs
