Classical Music in Video is an Alexander Street Press database which includes performances, interviews, documntaries, lectures, and masterclasses of Classical Music. Unlike Opera in Video, which focuses only on opera, classical music in video contains different types of classical music performances from instrumentalists, choirs, and solo vocalists. Users can search for specific videos or opt to independently explore the collection with the extensive browsing categories available.
Here's a visual sourced from Alexander Street Press that demonstrates the expanse of the collection.
