I just downloaded the БГ 50 CD from allofmp3.com (a nice place to get music on the web, by the way). When I listened to the album I first wondered why I couldn't hear the audience on a live recording. Then I realized that БГ 50 is no live recording. It is just a collection of various Akvarium favorites, often in quite obscure versions (e.g. "Adelaide" not from Equinox but from Territory). And not only is this not a live album, this is also not a very good compilation: the order in which the songs are presented looks pretty much like "random play". So, for anyone interested, БГ 50 is definitely not recommended. It would be a great concert recording if it was one (take a look at the setlist!) but as a best-of sampler it is quite rubbish!
