Tempi seem somewhat on the fast side, which will make it fit on one CD without problem. From what I heard, it sounds like Mahler's revised version for the first performance of Parts II and III of the work were used, instead of the original 1880 version, like Kent Nagano's recording. Though sound from computer speakers isn't the best, it sounded like all sections of the ensemble ought to sound quite good on a regular stereo system.
