I found an awesome resource I want to share with you!
Radio 4 in The Netherlands has a website with a wealth of pre-recorded concerts that you can listen to for free online. You can also listen to the station live. The concerts typically feature world-renowned artists (for example, here is the link to a concert by The Tallis Scholars).
Here is the page where the concert listings begin. You can also filter the results by genre (in the blue box marked “Alle genres”, click the white down arrow to get a list by instrument or type of composition) or by era (in the blue box marked “Alle tijdperken”). I believe the words should be discernible, even if you don’t speak Dutch.
Here is where you can find a list of artists performing in the concerts. This is an impressive list.
They also offer a weekly free download (you can find it on the Radio 4 home page). This week the “Download van de week” is by Ludwig van Beethoven, Piano Concerto No. 3. Sweet! If you encounter difficulties with Google Chrome, try Internet Explorer or Firefox, they worked just fine.
There is also an assortment of podcasts available, which is fantastic if you understand Dutch, or if you’re linguistically adventurous!
