Discography of Brahms, Piano concerto 1, op. 15

Who knows of a complete discography or comparative reviews of various interpretations of the piano concerto in D-minor?
If you are under 50-years-old, you may have enough years to digest it all. If you are over 50, wait till the next go-around.

You may want to send an e-mail to the International Piano Archives at the University of Maryland-College Park. One of the 2 or 3 greatest minds when it comes to the piano or piano recordings, Donald Manildi, is the Curator. He was the one who did the Arthur Rubinstein discography for the Harvey Sachs biography of the pianist. The discography garnered more attention and kudos than the actual bio.

I kept Rubinstein/Reiner on RCA and Fleisher/Szell on CBS in my library and gave away 20 other recordings for others to enjoy this marvellous work.

It's not complete in any sense, however an excellent collection of reviews of classical music can be found in "Third Ear" Classical Music, The Listeners Companion, edited by Alexander J Morin, and published by Backbeat Books. Over 1200 pages, including brief comparative comments on 31 different performances of the Pc's 1 & 2.
The Schwann Opus Catalog will contain a list of every currently available recording of the work. A list of every recording, whether in print or out, might exist somewhere, although I've never seen one.
These are not "complete discographies" but rather books of selective recommendations of classical recordings that in the opinion of the editors/contributors merit consideration. In the order of their usefulness to me:
(1) The Penguin Guide to Compact Discs and DVDs, ed. Ivan March et al. The 2003-4 edition has 1566 pages. Huge, comprehensive, well established; sometimes galling to American users because of its British chauvinism. Very useful.
(2) Third Ear: Classical Music: The Listener's Companion, ed. Alexander J. Morin. 2002, 1201 pages. The new kid on the block (this is its first edition), but also huge, comprehensive, and damned good. American in origin, so not subject to the pro-British bias of Penguin and Gramophone. Very useful.
(3) Gramophone Classical Good CD Guide, ed. Emma Roach. The 2004 edition has 1433 pages. Also huge, comprehensive, and well established, but less comprehensive (and I think less useful) than 1 and 2 above, and also marred by British chauvinism.
Some classical music buffs also fancy the Rough Guide to Classical Music (British) and Jim Svejda's Record Shelf Guide to Classical CDs (American), both of which are more elementary and much less comprehensive than the 3 recommendations above, but some might find them better suited to the needs of the newcomer to classical music. (I have both but find I rarely use them.) Svejda's book suffers the inevitable limitations (shared by none of the other books listed here) of one man trying to cover the entire field of classical music (and Svejda, who also fancies himself a movie critic, certainly has his limitations).
To the two fine classic recommendations of Vvrinc above (Rubinstein/Reiner on RCA and Fleisher/Szell on CBS/Sony), I would add one more "golden oldie": Curzon/Szell on Decca/London (engineered by the great Kenneth Wilkinson). If you seek more recent performances, I don't think you could do better than to go with the pre-eminent Brahms pianist of recent decades, Stephen Bishop-Kovacevich. He did an earlier fine version with Davis on Philips, and a more recent one with Sawallisch on EMI that is even better.
