Symphony 5th - best recording


My 3 year old son heard this on some kids show and wants the CD, I figured I can use this as an excuse to spend some $ on the finest recording I can find...any suggestions?

It might be Mahler? Or Shostakovich? There are several "5ths" that are still world famous (even if they did not appear in "Clockwork Orange" which, btw, is not suitable for a three year old!)
I slightly prefer Reiner's to Kleiber's, although the latter is available on SACD (the DG sound might still be a bit harsh). The former will probably be re-issued on SACD. Szell with the Concertgeboew in a 24/96 re-mastering is also excellent. Boehm's VPO version is more relaxed than the others.
Sorry for the vague post, yes, I meant Bethoven's 5th. The program that he saw is Little Einsteins...it's about 4 little kids in a rocket that travel around the globe. At the beginning of each show they introduce the music that they will be hearing.

Thanks for the great recommendations everyone.

Thanks for the compliment Newbee...here is a link to the show in case you have kids of your own:

Now that we know for sure, I'm going to second Rustons recommendation. FWIW the performance is so outstanding that if you like this symphony you won't care about whether its the best 'audio' version. It is propulsive, grabs your in those first notes and never lets the tension relax. This is one of the few performances of anything that I feel might actually be definitive! :-)
Of course, Beethvoven! I don't have a favorite recording of it to recommend, but you might also might want to try the 6th for him--it's in Fantasia after all! Plus it has a story line that goes with it (that you could embellish). Anyway, good luck.
