To find recordings by a specific conductor, use the Advanced Search interface in LibrarySearch. Search the name of the conductor as author/creator, select "Audio & Video" as the material type, and select "UO Libraries" or "Music Collection" as the search scope.
You can also search for the title of a composition. If the composition has an opus number or other type of composer number (such as BWV for Bach or K. for Mozart), search for that as the title-- this is particularly useful for searching for works with genre- or form-based titles such as concertos and sonatas, where you might get a lot of results for things you don't want if you just search the composer and title alone.
See the Audio tab in the main Music Research Guide for a list of our streaming audio databases.
