I'm planning to buy a few, however, as those are quite pricy (import), maybe, if you have seen any of those, you could give me a tip:

Coda (Limited Edition + aSync Live Performance) - planning to buy
Coda (just the documentary)
Playing The Orchestra 2013
Playing The Orchestra 2014
Trio Tour (Live in Europe 2011)
Trio Tour (Live in Japan 2012).

Obviously, some of the live shows are for the most part the same, but which ones are better performances? 2011 vs 2012; 2013 vs 2014?
