I tried playing this and the original simultaneously to see how I did in terms of timing, that being one of my impressive collection of Achilles heels. I begin by edging ahead, then the strings overhaul me in the middle, and finally we breast the tape together. Not good - but not too bad either.
Tangentially: I was listening to a programme about the Institute for Advance Studies in Princeton the other day, and it put me in mind of the year (1999) my brother was employed by them as their Composer in Residence. Isn't that just the coolest gig ever for a geek?
Not that he is a geek, in fact; but I'm happy to squee retrospectively on his behalf.
