To me this was the beginning of the end for the Wilson sisters. Sure, there are some okay songs on here, or so I thought until I recently replaced my vinyl LP with the CD. These songs sound so dated that I can't believe I used to like them. To put it mildly, this album was Heart's contribution to the 1980s "hair band" movement. Synthesizers and drum machines have taken over for Nancy and Howard's guitar playing. Dreamboat Anne and Little Queen still sound as good today as they did when they were released. This CD does not.

Ex Output:
Negative

If you want your faith in market forces and low taxation reinforced, this is a straightforward, but blinkered attempt to make you forget all about government regulation. Funny that west-European countries with bigger taxation and more government influence have less crime, better education, better health care, better TV programmes than the US. They also organise their politics better, so that the tax money is better spent. It did set me right on one or two points, and parts are written in a spuriously funny way, but it is too biased to be really informing . Clearly the writer has never listened to people he doesn't agree with.If you have an open mind compare this dangerous nonsense with the writings of Naomi Klein to see how unfettered capitalism works out in practice.
