Minor Chromatic Mediants

Please recommend me some music from the 19th or early 20th century that uses chromatic mediants in a minor key. I particularly like i-vi-i progression (Amin - Fmin - Amin in the key of A minor), like the Imperial March from Star Wars. Also what's the earliest example of Composers using a major or minor triad built on the note a tritone away from the tonic?

I can't recall an specific passage of a work with it but I'm sure you can find them in Grieg music...

btw "mediant" is the name of a degree of your scale, not of an interval, is a very common mistake, not any 3rd you see is a "mediant",

i.e. in C major your "mediant" will be the chord of E minor, nothing more, not the A mediant of F major, B mediant of G major etc...

is like "dominant" is also a degree name, your dominant is G major chord, not any 5th you can find.

The term mediant can also refer to the relationship between two triads, not just the III (or iii) chord of whatever key you're in. For example a diatonic mediant relationship exists between V and viio, and a chromatic mediant relationship exists between V and (b)VII. But I'm talking about chords that have a chromatic mediant relationship with the tonic of a minor key, specifically when the III and VI chords in a minor key have their thirds lowered to make them minor. Thanks for replying though.  

And yeah I know, not just any chord a perfect fifth above another chord is it's dominant. It has to be a major triad or Dominant 7th chord in order to function as one.

Anyone else want to join my movement to clean-up and simplify music theory terminology?  As with latin names for species… many common names in many languages, but one definitive, clear-cut way to say it that is common for all folks of all language backgrounds as well.  Anyone else?  I'm sure it will take a fat, well-paid committee about 50 years to work out how to do it, and I graciously volunteer myself for the salary.  I mean the job.  (:

Shosty Sym. 11 ? too new right ? you want it older examples... let me keep thinking...

Thanks, that was a good example. I guess this is something composers didn't start doing until the last 100 years or so.

A chromatic mediant is formed upon III of scale. Diatonically, as SYS, this usually is mediant. For example: in C major the III would be E minor.  A chromatic mediant would is bIII, Eb Major, or E major. Same goes to IV: A minor. That could be change to Ab major or A major.
