 While the album originally stood on its own, in 1990 it and the preceding and subsequent albums ("Behind the Gardens - Behind the Wall - Under the Tree" and "White Winds") were re-released as a two-CD set entitled "Trilogy," suggesting they collectively constituted a single musical entity.The full titles of the first two albums lend credence to the suggestion that the three albums are thematically connected.The full title of the first album is "Behind the Gardens—Behind the Wall—Under the Tree..." The ellipsis at the end suggests a continuation.
