juanmanuelfangioli,
One of my favorite recordings is Rachmaninoff Symphonic Dances, Dallas Symphony, conducted by Donald Johanos, 1967. The companion recording of Copland works (Rodeo, Fanfare for the common man) shares the same recording technique. They were done in the auditorium of Southern Methodist University. These recordings were audiophile demo spectaculars in the mid 70's when I got started as an audiophile. The recordings are close miked with minimal hall sound. They sound like front row center. Most other recordings of these pieces are distant with more ambience. Musical clarity and detail are nearly completely lost in the soup of ambient smearing. That's what you get with 20th row seating.
