hmm i love so many things about each of those i listed, but i'll start here for now:
the Rosza Op 31, man what an incredibly energetic work! to me it sounds like what Bartok might have put together were he charged with having to make film music for a 'sand and sandles' flick.
ala

(to be fair Alex North did an amazing job w the Spartacus score)
but one place that stuck out to me in particular when i first listened to this (i admit i had to stop my first play of it and rewind just to hear it again ) is the cadenza of the first movement, it is one of the most bitchin' 90 seconds or so i think has ever been written into a concerto (note i said one of, not 'THE" most)





i.e. six minutes and 40 seconds in... man , epic!
