Query: A change for the worst

Due to merengue becoming such a force in music, Fania recurred to new sound to try to fight back. Unfortunately, they turned to a disco-ish sound as they did with "Delicate and Jumpy" and other numerous albums during 5 or 6 years. Social Change does incorporate some jazz elements such as piano and soft horns, and I actually enjoy jazz (specially latin jazz)but, this album to me is a miserable failure in many aspects. As I said earlier, its sound is too reminiscent of disco and not even Gato Balbieri could save this album. I would definitely stay away from this one as this is not the usual Fania.
