As history develops through centuries, so does music... "Dance life" wants to represent the best Electronic Dance Music of each 2 months period, produced mainly in Italy and Europe but also worldwide. So it's not a selection of the greatest chart hits of that period, but rather my own personal selection of the most interesting tracks from a "music evolution" point of view; they were all published at that time but sometimes they became popular only later or actually never, and they were (unfairly) forgotten.
1990 - Spring (Mar/Apr): these are the tracks from the time the Hubble space telescope was launched.
