When I say this was a challenging listen for me it's more a reflection of my lack of familiarity with this musical form than a dislike of what you've done. In fact, I enjoyed the challenge, and your treatment of the material is quite nice. I did go back and listen to a K&K Philharmoniker recital of the chorus for reference. (I know it's a well known work, just not well known to me.) Anyway, my only critique is that your vocals get quite loud relative to the band in the second half of your arrangement, and you may wish to set them back a bit, especially near the end. Looking forward to your next one!
