Remember the book Potatoes Not Prozac - the one with the dietary plan to stabilize blood sugars and thereby alleviate depression?
Well, that's how I feel about the power of Bossa Nova. Yes, it's still timeless and classic nearly 50 years after Getz/Gilberto's The Girl from Ipanema took the US music charts by storm, but I think it CAN alleviate all sorts of sour moods - depression included.
While I really like this version of Meditacao (meditation in English) by Carmen Cuesta, I love it by these guys. Seriously, this album is desert-island-worthy material. If you don't have it, you need it - your pleasing personality depends on it.
