If not their best release, it's probably their most immediate and accessible. "Moya" and "BB3" are easily some of the best songs in their discography, not that they have many songs.
My favorite Archers release, maybe second to only All the Nation's Airports. Worth listening to for track flow alone, and it's made up of five of their best songs.
A great link between In/Casino/Out and Relationship of Command. This is what I like most about EPs, since they give room for experimentation in between records.
