That disc [Aho theremin concerto] looks delicious. The works aren't even on allmusic yet, so I would've never known!

Cheers

So far I've seen it only on eclassical.com, where it turned up last week:

[Elgar's Ghost]

Typewriter also used in Satie's 'Parade' (1917) - although collaborator Jean Cocteau was said to be responsible for its inclusion, plus a siren, foghorn and other novelties.

Mozart Keyboard Concertos played by Jos van Immerseel on fortepiano with period orchestra.

To conservative listeners, this may be joltingly unusual instrumentation.

Miklos Rosza used a theremin in his Spellbound Concerto.

I'd also add Khachaturian's Third Symphony, which 18 trumpets and an organ. Not unusual instruments, but a rather unusual combination.

There is also a piece by Louis Andreissen called the Nine Symphonies of Beethoven for Orchestra and Ice Cream Bell. Not a great work by any means, but it's fun to listen to.

I thought of a few more:

sleighbells: Mahler's 6th symphony, Prokofiev's Lieutenant Kije
cimbalom: Kodaly's Hary Janos, the orchestral version of Debussy's La Plus que Lente
vibraphone: Korngold's Die tote stadt, Walton's cello concerto
cowbells: Mahler's 7th symphony, R. Strauss's Ein Alpensimphonie

The cimbalom is kinda neat. I would say the vibraphone hasn't been an abnormal instrumental choice for a long time, though.

Sleighbells? Don't you mean Mahler's Fourth Symphony?

...one more: a Charles Ives work uses a Jew's harp. I think it's Washington's Birthday.

You are correct. Around my house, Washington's Birthday celebrations would be unthinkable without Uncle Amos playing the Jews' Harp.
