Under individual works are listed all commercial recordings known to me. If you know of other recordings, please get in touch; smilarly, if you find errors or are able to provide actual recording dates. I am grateful to Miguel Montfort and other correspondents for alerting me to many issues on unfamiliar labels.
Piano rolls made by Medtner and others are not listed unless a sound recording exists. They are listed in the BIRS article Medtner recordings.
Recording dates can be difficult to establish and some may be inaccurate. A number of dates from the LP era are taken from the IPQ discography but I have found other dates in the article to be incorrect, though usually only by a year or two. The BIRS discography only dates non-commercial recordings. Dates given as circa are usually estimated from the release date. For Melodiya LPs many releases can be dated from the catalogue number. For a few LPs neither the recording nor the release date could be established.
Downloads are listed if this was the sole or primary medium of release, in addition to a few that are (legally) free. Some record companies license CDs for download. I have not attempted to list them as the number is continually growing; an online search will find them. Some vendors offer instant pay-per-track, while others operate a subscription service. There are of course many pirated recordings circulating on file sharing networks. Be warned that many mp3 files are digitised at bitrates below 256kbps, the minimum generally regarded as giving CD quality.
nla means the recording is not listed in the issuing company's current catalogue, without regard for whether it has UK distribution. A deleted CD is not given as nla if it is still available as a download. This applies to deleted Chandos and CRD discs which can be purchased from the Chandos website, many of them in a lossless format. I have not attempted to keep up with deletions, so the absence of nla does not necessarily mean a CD is still available.
Deleted CDs can often be obtained secondhand, and sometimes new from suppliers who acquire stocks of deleted items or "dead" labels such as Russian Disc. Amazon (.com, .co.uk and .de), ebay, russiandvd.com and MusicStack are good places to start.
For unfamiliar labels, a Google search will usually bring up a supplier. Presto Classical and CD Universe sell lesser-known labels and some deleted issues.
Ruslania offers a good service and has some Vista Vera issues, but not all of them. You need to search on both Medtner and Metner.
Mejoueva's recordings on Denon and Wakabayashi, Bekhterev's on the Camerata label, and some other Japanese CDs can be ordered online from HMV Japan. Amazon Japan will also deliver internationally, but their shipping charges are high.
The French site cdandlp.com is a trading platform for sellers of new and secondhand recordings. The Russian seller rarervnarodru lists many recordings that are hard to obtain outside Russia.
A discography of commercial recordings of the solo piano works and concertos was published in the Autumn 1998 issue of International Piano Quarterly. An earlier discography (1978) covering all works was published in the BIRS journal. The latter includes BIRS tapes of BBC radio broadcasts and some private recordings by Edna Iles and others. Melodiya: a Soviet Russian L.P. discography lists Melodiya vinyl releases up to c.1975. The discography in Flamm's thesis gives a complete listing of Medtner's own recordings (taken from Barrie Martyn's BIRS article) and a partial list of other interpretations, without recording dates.
All of these sources have been consulted in the compilation of the present discography. Where possible I have checked the accuracy of the data against copies of the LPs/CDs or alternative sources. Significant errors (e.g. incorrect works) or discrepancies between the discographies are mentioned in the footnotes.
