There are four known risk factors beginning with "f" for a gall bladder. These are: female (female), fat (overweight), fourty (over forty) and fair (blonde). That should be the description of the target group of this singing duo pretty much. And you can hear that the music also. It is positive that both singers of professional singers and are actually and really can sing. The song playing with the different tones of voice of both and that makes them partially something interesting. Yes, I know, musical taste is subjective. But sentimentality is sentimentality. The singers just sing those heart-Weltschmerz Kitsch to deter genuine and thus changing feelings to get close. Penetrant, as I said, is calculated here on the not mastered subjects of a certain target group. It is just not perceived music, but the calculus on the drawing board. And you can hear that. They call this album "Best of". This may be understood as risk warning.
