i am intrigued by this too, but i will say that heroes and thieves is my least favorite produced album. the instrumentations seem overdone and the vocals not enough. then the drums and instruments sound very processed while the vocals don't and it feels off putting to me like that. also, some of the melodies just feel cheesy. i realize i'm the minority of fans who don't like the album. actually, my friend just interviewed V and she said that she wasn't a fan of the cover and felt like they did too much and rushed it.
