I stumbled across a blog post this week (can’t remember where) that had a video embedded of the men from the Together for the Gospel Conference in 2008 singing “Before the Throne of God Above.” I probably watched it a dozen times or more, I enjoyed it so much. So I went to go check out the album at the Sovereign Grace Music store and found out that they’re having a special sale all February. That means it ends today. All music albums are only $5 for the downloadable version and $6 for the CD version.

I picked up the Together for the Gospel Live MP3 Download Set and have been thoroughly enjoying it. I heartily commend it to you.

The folks at ReformedAudio.org have just completed an audio version of J. Gresham Machen’s classic work Christianity and Liberalism. It’s available in 11 MP3 files and runs 5 hours 44 minutes and 36 seconds. They are making the audio and a PDF of the book available free of charge.

To learn more about Christianity and Liberalism and Reformed Audio, watch this short introductory video (embedded below).

Update: To the best of my knowledge, Machen’s work is not yet in the public domain. Unfortunately, it was published and copyrighted in 1923. Books published in 1922 or earlier are automatically in the public domain. Books published between 1923 and 1963 are only in the public domain if their copyright status was not renewed. Google has a nearly exhaustive list of copyright renewals, and according to their records, the copyright status of Christianity and Liberalism was renewed in 1950 by Arthur W. Machen (his son?). If my understanding of copyright law is correct, that would mean that one would need to obtain permission from Arthur Machen or the current copyright holder before producing any editions of it or distributing it for free or for charge. I’m not sure if the folks at Reformed Audio have obtained permission or not, but there is no indication in their audio files or PDF that any of the content is under copyright. I just sent them an email to inquire. Perhaps the simple answer is that the copyright holder has released it into the public domain. I hope that’s the case, because I’ve been wanting to get this book in Logos Bible Software for a long time.

Update 2: I corresponded with Ben of Reformed Audio, and he believed Christianity and Liberalism to be in the public domain based on Ed Walsh’s assertion on Reformed.org. However, Shane Rosenthal also maintains that Christianity and Liberalism is still under copyright. Based on the evidence I’ve seen, I’d encourage you not to download or distribute this content.

Update 3: I’m happy to report that Ben was able to get in touch with someone at Eerdmans, who confirmed that they still hold the copyright. He granted Ben the permission to continue to distribute the audiobook free of charge. So feel free to download it.

Amazon has four free MP3 albums that you might be interested in downloading.

Gaffin Jr. on “The Mystery of Union with Christ.” Gaffin delivered these messages at Matthews Orthodox Presbyterian in March of 2005. I’ve downloaded them and listened to part of the first one. It looks to be a very good series. They are available as free downloads courtesy of SermonAudio.com.

Amazon is currently offering Guitar Sampler, a 20-track album of classical guitar music, for only $2.99—the price of just three individual tracks in the album. I downloaded it last night and have been really enjoying it. If you like classical guitar, you’ll most likely enjoy this album. You can listen to samples of all 20 tracks to find out.
