One possible reason for the 'blandness' (or other subjective adjectives) in the Cavies' music is Saucedo's writing style. He has admitted that when he writies music, he focuses first on the chordal structure of the piece and then works in a melody that fits on top of that. Now, I don't know the first thing about composing, but when he admits he loves the chords more than the melody, I could find that to be distracting for those that listen for a melody.
(He conducted an Honor Band I was in last week, and we had a question session with him where people asked him about how his mind rolls when he writes.)
