I've heard a few different recordings of both the Concerto for Orchestra and Dance Suite by Bartok (and I've also played both of them in an orchestra.) In my opinion, this particular recording, while not the greatest ever, stands out from others because of the intense vigor which is always present, whether simmering beneath the mysterious opening melodies of the Concerto for Orchestra, or the gargantuan glissandos in the Dance Suite. Solti, like Bartok, was Hungarian (and he actually studied piano under him at the Budapest conservatory [which I was fortunate to visit this past summer],) so I think he captures the rustic flavor of the pieces very well, instead of just glossing over the less pretty aspects of the pieces as some orchestras are wont to do. All in all, a record that definitely has you dancing in some places, and staring into space in awe of eternity in others. Part of that is Bartok, and part of it is Solti.
If you haven't heard the Concerto for Orchestra, it's one of the masterpieces of Contemporary Classical music. It's nigh near impossible to describe music in words, so just give it a listen. If you've heard it before, I think you'll be pleasantly surprised by this presentation.
