You forgot the Youtube link? Want to hear! For some strange reason I cannot get enough of this etude, I love it...
i don't know that it's been recorded recently if at all.
I don't even know that it is that well known in clarient circles, the chiopin nocturnes arr for clarinet and piano are a lot more popular, i don't get it (but the OP might be interested in those too).

to the OP, boosey and hawkes publishes the piano reduction and solo score to this, the andante is super pretty
