Thanks. I mentioned Atterberg's Third Suite because like Szymanowski's, it too possesses the sound world that is pretty exotic in its own right (principally its second movement). I have to confess I was not familiar with the First Suite until you mentioned it. :o
Also, I should mention Lehar's Giuditta as pretty exotic in its own right.
Hmmmm....I don't recall anything particularly "exotic" about the Third Suite-will have to re-listen to it! Re the First Suite, a chamber reduction of it has been recorded (on Marco Polo), but, of course, I would definitely welcome a recording of the orchestral version as well as all of the other suites! Hopefully Jarvi will get around to them and other unrecorded orchestral works by Atterberg in his series for Chandos.
