There are 22 box sets of classical vinyl albums and some of them I believe are original recordings from the actual concert before released to the public as albums.
Each box set has its own price (some will be $50, some less, some more) but, if you buy them all, you will get a deal.
Some of the artists include Mozart (my uncle was the founder of the Carmel Mozart Society and brought all of the musicians from Salzburg for the most part), Beethoven, Bach, Chopin, Vivaldi, Schumann, Scarlatti, Strauss, Schubert, Ravel, Brahms, Haydn and several Archive Productions of famous symphony concerts done in the 1950's.
There are also individual albums. This is truly a beautiful collection of music by someone who really knew music!
If you would like to inspect the collection, let me know.
