Sorry it’s a bit late. Enjoy it anyway!
The City of God, a book about practically everything. Read at a brisk but quite comprehensible pace by a single reader, and totally unabridged. Very interesting, whether you like Roman mythology and folklore, politics, or theology. If Charlemagne thought it was fascinating, you’ll like it too! From our friends at Librivox.
The Enchiridion, a treatise on Christian piety, faith, hope, and love. Also from Librivox.
The Confessions, St. Augustine’s autobiography. Coming soon from Librivox.org, already available in part.
From me, of course, Of the Catechizing of the Unlearned and On Christian Doctrine. Oh, and the contemporary Life of Augustine by personal friend St. Possidius.
“The Petition of St. Augustine”, a really nice five-minute choral setting by Dr. Erik Reid Jones of something St. Augustine wrote about singing and perseverence in the Christian life. The MP3 link on the page covers the whole piece. The group singing is the choir the composer directs: The Master Singers of Virginia.
“St. Augustine’s Pears” by that old Christian Rock band, Petra. Not bad.
“I Dreamed I Saw St. Augustine” by Bob Dylan.
Mike Aquilina on St. Augustine, on the Catholic Men’s Podcast.
Fr. Z discusses St. Augustine’s sermon to newly baptized Christians.
Stuff I haven’t listened to, but I’m linking to ‘em because they’re there:
Fr. Kubicki on St. Augustine, at archive.org.
Theopedia: includes several audio lectures which may or may not be crazy talk. 
But heck, considering this week we’ve seen someone claiming that no Christian should read the Church Fathers at all because they’re all heretics and will suck you into Rome like a giant Early Christian black hole of DOOOOM!, I’m feeling very supportive of anybody who’s into patristics today.
