With the given scenario, that's not possible, because you told KPA that all 
photos of George implicitly have the tag "Scream". Look at it this way the tag 
"Scream" means "A member of the music group Scream". Even if George is fishing 
alone by some lake, he is still a member of the music group.
If "Scream" is not an inherent thing to all "George" photos, you should keep 
both tags separate.

way you can search for photos of the band-members of Scream (Persons->Scream), 
that were shot in the context of a scream concert (Keywords->Scream concert).

"Scream world tour 2012" or "Scream live at New York" as sub-tags to "Scream
