The Lost Archives 4 contains most of the remixes that have ever been released on Audiosculpture between 2001-2013. This remastered edition also features 2 additional bonus remixes that have never been published before, due to some distribution issues in the past. The first one is a Sculpturism remix of their Electribes track, while the second one is an unreleased Counterpart remix that has been produced almost 8 years ago.
