Fair point that recurrence is already evident in their body of work thus far. I should have underscored prominent - or said a bit differently, hummable - rather than recurring as my main area of interest. I can hum multiple John Williams and (early) Danny Elfman themes on the spot, but I wouldn't dream of trying the same for even the more melodic existing TRAR scores. Since TRAR obviously know their way around hooky melodies and bombast, I'd be interested to hear that expertise applied in a film context as well.
