Concerning Respighi; There are a few skaters that have used it a U.S. Nationals, but not successfully. I think the problem may be the dynamic shading of his music. When I listen to Pines of Rome I find myself having to adjust the volume more than once. If I'm in the car, I can never hear half of the catacomb's section and I can't begin to get the full effect of the Appian Way. I think Respighi's music is enjoyed best in live performances.
I'm sure an expert sound engineer could overcome these issues. It only needs a skater with some funds to cut the music well and Pines of Rome could become one of the great skating "warhorses".
Just like I love those chords in Daphnis and Chloe, I thrill to the way that "Pines of the Appian Way" gets all the way there and leaves me feeling complete. With the right skater it could be a masterpiece.
As with Daphnis and Chloe, I can't find a really good version of Pines of the Appian Way on youtube.
