The only area of his work I know at all well is the violin sonatas and even then I only know no. 3 and the Impressions d'enfance really well. Which is silly of me really since they're such wonderful pieces I wonder why I haven't investigated further... Leonidas Kavakos made some wonderful recordings (3rd sonata, Impressions). As did... George Enescu, with Dinu Lipatti (2nd and 3rd sonatas).

Here's another great 20th-century artist of Romanian birth by the way:

I've very recently acquired the EMI/Foster recording of Oedipe, which isn't readily available now, plus a series of recordings by the "George Enescu" Bucharest Philharmonic Orchestra conducted by Cristian Mandeal on Arte Nova. The symphonies are much grittier than you might expect of the composer of the Roumanian Rhapsodies. I've saved Oedipe up for half-term listening... this thread may well inspire me to give it a proper listen this evening, having only heard the Prologue so far. There's a useful synopsis here:

http://en.wikipedia.org/wiki/Oedipe_%28opera%29

Yehudi Menuhin wrote a foreward to the Oedipe booklet, in which he speaks most highly of the opera and explains how Enescu kept the score with him at all times, working on it night and day.

I fear KING OEDIPUS will make somewhat penitential Half-Term listening, Inquisitore!     I have only heard it live at the Bol'shoi, where Romanian National Opera were on tour. Half the audience didn't come back after the first interval, and by the end of the second there remained only a diehard few.  I stuck it until the end, but I can't say I enjoyed much of it.  The production didn't help it, nearly 30 years old, looking extremely tatty, and in the "stand-and-deliver" style.  I mention this because it's probably the production still in repertoire in Bucharest   Romanian National Opera have a wide range of productions (I have seen them once or twice on their home ground, too) - like most E European countries they mostly have an E-Bloc-legacy of "politically inoffensive mainstream stuff" - Boheme, Traviata, Carmen, Forza, Rigoletto, Merry Widow, a few works by local "Party Darling" composers, you get the idea.  They are the kind of productions The Fiends Of English National Opera would like - ie set in a kind of fairyland past, with painted backcloths, historick costumes, and as little movement as possible.  At moments of death, disaster, treachery etc the single-scheme lighting schema will employ a bit of red backlight. Most of the best orchestral players have long since moved abroad in search of pay above pittance-level, unfortunately.  The same is true of their more talented producers and designers (viz Marie-Jeanne Lecca etc).

If you possibly get a chance whilst in Romania, Sighisoara is well worth a visit (probably the most beautiful city in the country), and their opera-house (although tiny) has a few good shows.

Theres'a an amazing string octet I heard on ttn, molto energico,and a symphonic suite or 2 that are efectively symphonies. On the basis of occasional hearings I think the guys' a maverick genius,but needs unbuttoned and ritmico performance.

Only just seen this, DB, but I'm thrilled that you've discovered that piece!
