Look into Kontakt sound libraries for good acoustic instrument sounds, at least I know it's a rather good sampler for orchestral sounds. That being said they're normally rather expensive. If you just want something free check out soundfonts, there's TONS of them out there -

I'm glad you liked the break!
Actually though most of that was done with actual players, the trumpet was all performed by our sound designer for the project Ken - the alto sax was played by Cyril.
As for the harps and acoustic rhythm guitar that was factory libraries that came with Kontakt.
