I bought myself a Christmas present: The J.R.R. Tolkien Audio Collection. I have it on cassette and was going to put this CD version on my Christmas wish list when I realized it was easier to buy it for myself than to try to explain it my family! ("No, not the audio books, the audio collection...")
This collection features J. R. R. T. reading bits from LotR and Christopher reading selections from Silm. If you follow the link to Amazon, this work is described as abridged but it includes more than my old cassette version! The quality of some of the recordings (made in the 50s) isn't great but that's a minor complaint. It's worth the inconvenience to hear J. R. R. T. himself reading. A bonus: the set includes the unpublished poem "The Mirror of Galadriel," which was edited out of LotR.
I highly recommend this CD for anyone who like the audio books or is interested hearing J. R. R. T.'s interpretation and pronunciation.
