Hmm, you just can't compare them, IMO.
The '91 show was hard and fast and challenging but it was fairly faithful to the Sebesky and Kenton with musical development over time. It essentially breaks cleanly into three clear main sections.
The '10 style is that really mixed up, blenderized stuff that BD have been doing for a few years where there is little development, recognizable snatches come and go, begin and are interrupted and reappear for a fraction of a second only to immediately change key and so on.
