For The Royal Treatment, groups and artists from San Francisco's City Of Tribes label were remixed by Californian dance producers, including the well-known Scott and Gavin Hardkiss.

City Of Tribes' star musician, dijiridu player Stephen Kent is sampled from the group Trance Mission's "Go Play Outside?; track by the Baroness, and recontextualised into an acidic dub-house groove that mutates into hard funky hip-hop beats, and features dubbed elements ? so yes, expect this compilation to display that eclectic West Coast sound that runs the gamut of rave culture.

For the original sound of the City Of Tribes groups, seek out their latest compilation, #4 in the Event Horizon series, which includes a live version of the Trance Mission track that was remixed above.

Lights In A Fat City synthesist, Simon Tassano, also provides a richly textured tribal-ambient track, the unreleased "Tropic Of Texas." If you don't care for rhythm in your ambient music, don't miss the atmospheric moment provided by the Venezuelan quartet Incierto Insecto.
