This is a nice package if you are on a budget and you don't have any of them ( I just had to have Rio, what can I say). If you are not on a budget and you can still find them I would reccommend getting the Rock Montreal +Live Aid Blu Ray, the live at Wembley 2 cd / 2 dvd import and the Hungarian Rhapsody Blu Ray. Then if you want another one get the Live at The Bowl. Montreal and Wembley are my two favorites, and if you can only get two those would be my picks.
(5-2014 update. I see where the price went up since I bought. I would reccommend price shopping the concerts. Rio is not a must unless you are compulsive like me. )
On to this box set. It is packaged nicely. Each concert is in it's own case and housed in a box. I was pleased with that , I hate the new trend toward paper sleeves. I docked a star because in my opinion they really should have included the Montreal blu ray, + Live Aid along with the dvd version and the Hungarian Rhapsody blu ray and dvd. They did not include Live Aid or Hungarian Rhapsody at all. The Live in Rio is the weakest of these releases and possibly should have just been considered as an "extra" The distance shots are somewhat grainey although the close in shots are very clear. The set list is shorter than Montreal and Wembley. Two songs I was looking forward to were Liar (one of my favorites) and It's A Hard Life. Liar was a shortened version Hard Life was complete. I was surprised that I enjoyed Love of my Life, Freddie hardly sang any of it, the crowd sang almost the whole song. I usually don't like that, but his interaction with the crowd on the song was enjoyable. I can't speak to the sound really, I just use my TV speakers not a sound system. The sound was fine thru the TV.
