This album from 1998 has been brought to my attention by Kaliyuga Pro.
He bought it a few years ago on ATAK not knowing much about that crew, except that they were from California. The list of the members doesn't give much clues either: Ill Nature is Serge The Wrecknition, M.E.R.C.U.R.Y. (no relation to Sunset Leagues I think), Maximum Styles and depending on the cd booklet: L-Element and Concept, and on discogs: Sovereign and Elly Estro.
There's also a bunch of featurings by various mc's I never heard of that seemed to be grouped under the name The I.S. Chapter. The production is handled by Serge The Wrecknition, The Butter Thief and Concept.
The music is pretty good, it's actually a surprise it didn't get any more attention, probably lost in the ocean of releases at that time. A vinyl version of this exist, you can found it easily on discogs although they tend to be a little pricey.
It's about time people check this album!
