A little web research has turned up 8 Anda recordings, not necessarily
all available.
From the discography on the Geza Anda website,
http://www.gezaanda.ch/index.php?site=gezaanda_diskographie_2009

DGG 2535 364* [1979],
DGG MGW 5225* (Japan) [197?],
DGG 457 967-2 [1998],
DGG 477 5289 [2005],
Brilliant Classics 93795 [2009]
but the discography somehow misses this one:
Freemason's Hall, Edinburgh Festival, 23 August 1955
BBC Legends BBCL41352
This and, I think, the 1956 Salzburg are the only live ones, but I could
be wrong.
I have the DG "Troubadour" set, which includes both the 1943 and the
1963. The same two are included on the Brilliant set, which looks to
me like the solo-piano portion of the Troubadour; but I don't think the
Brilliant is available either at this time.
