Watch the The Unison Gang online guitar lesson by Brad Carlton from Chord Studies: Flamenco Chords Vol. 2
So far we've been moving from an 11b9 chord to a major chord to create a flamenco sound. In this example, we'll use the sharp five sound along with the natural five implying the minor second sound of the Phrygian dominant scale. Also notice the triple unison E's at play in the upper voicings that help build the ominous sound of this progression.
