composer: Flor Peeters
Likely the most famous "Aria" written for the organ. Many fine recordings are already available here on CB.
I've disregarded the listed registrations and made use of the many fine voices found on this custom American Classic sample set. "Aria" seems to work with a variety of registrations. Maybe a step too far for some listeners, but I enjoy making use of what is available and sounds good to my ear.
