A bit of a helping hand needed with Glinka and Gluck

[musikalischer_wirbelwind_280]

Well, I came home a couple of hours ago after listening to the folks from the Orquesta Escuela Carlos Chávez give a splendid only-overtures concert.

And upon said arrival at my abode, I, probably trying to reassure myself that I was still me, looked up right away the piano solo transcriptions of the ones I didn't have yet (I know, you're just shocked).
    And while the hunt went well enough, with plenty of trouvailles to be had and all that, there are still two, out of the 6 played at the concert, that are giving me a bit of a headache:
Glinka's from "Ruslan and Ludmila" and Gluck's from "Iphigenia in Aulis".

The former I just can't find, at least not in a piano solo version, and the latter is certainly at IMSLP, but only the piano four-hand arrangements seem to be right, with the piano solo ones being curiously different, especially towards the ending, from what I listened to at the concert.

Does anybody know where they might be obtained? And in the case of the Glinka, if it even exists in the first place? I've looked it up myself already, but no luck so far... 

Cheers!
M.W.

Much appreciated, chap, as always, though the finances aren't at their very best right now (sorry, I completely forgot to add that I was looking for free arrangements... ), so I'll have to content myself for now with transcribing the Gluck from the 4-hand versions at IMSLP, and the Glinka will just have to wait a bit.

Isn't it a spot of luck that I've got the Coriolan and the Semiramide to keep me busy?

Cheers once more,
M.W.
