Ra uses an ominous, short narrative, entitled Fear, to set the mood at gloominess.
These short and curlies include "Far Enough," "Taken," and "Undertaken." The last highlight of the album is found on the acoustically strummed Swimming Upstream, which is a solid way to end a shaky album.
Even with the general mediocrity of Duality, I would still suggest picking this up because there are some sporadic hard rock gems to be found.
