Having been a fan of Moloko (Roisin's original band) since day one, I always found Goldfrapp to be a boring, sub-par version of both Moloko and to some degree Portishead.
Anyway, you really don't know much about Roisin if you just "discovered" her prior to Fashion Rocks a couple of years ago. She's been putting out material since 1995. Also, I "salivate" over her because the woman is indeed talented and worthy of every praise she receives. It has nothing to do with the public's lack of knowledge. Speak for yourself next time, bud.
I said I listened to Roisin BEFORE the Fashion Rocks show, that is just when the majority of people I know found out about her. I don't really get your comparison to Portishead but, okay, if you say so. Don't get me wrong, I like Roisin, I just hate when artists think they are the first and only of their kind. Arrogance and ego shouldn't belong in music and art but unfortunately nowadays it is hard to find humbleness in any field.
