2012 three CD collection from the Trance duo. After the success of the so8os compilation it was about time to bring u another exciting decade....the 90"s! The concept of so9os is a bit different from so8os. When they got deeper into it, they saw how diversified the "90s were, with a lot of different musical genres. So they decided to dig deeper and find out which songs still sound fresh after 20 years and really have a great production. They also decided to keep the whole dance music explosion from 1995 onwards aside. Not just keep their own career as musicians and producers aside, but also not to focus on only one musical genre. The first so9os release includes some massive tunes from P.M. Dawn, Saint Etienne, Baby Dee, Stereo MC"s and many others.
