Ligonier Ministries is offering three free movements of composer Jeff Lippencott's Post Tenebras Lux, a symphonic work.
"This symphonic work celebrates the five-hundredth anniversary of the Reformation." However, the three free works, at least, are completely instrumental. I didn't notice anything that sounded like a religious song until the third movement, and it was very subdued. These are just good classical music compositions.
Lippencott is the founder and music director of the Santa Clarita Philharmonic. Additionally to his credit, he was Emmy-nominated. He's written several successful film scores, etc., etc. Learn more about him by following the Google hits about him on
this webpage.
In order to get the free movements, you've got to be a member of Ligonier Ministries (it's free to join, although you may get some soft-peddled donation requests by phone a time or two), and go through a not-very-onerous shopping cart/checkout procedure. The freebies will be placed in your "member account," for downloading whenever you wish to do so.
I suggest that you start your exploration by listening to the streaming version, and such,
here on this webpage.
The zip file that I downloaded contained three MP3's.
