This is the 6th album from the Archives series of 25 albums, but also the first of the new collection (Emerald),  which follows the Ruby collection.

Emerald one offers eight tracks (all recorded in 2005, just as in the case of the Ruby five album), which tends to align itself more and more with pure electronic style of music, however even here different themes are approached, which surprise (Saxish, Arian Theme). The rest is a richness of sonic ideas and influences which very clearly express the variety of Indra in this area.
