At first a big "thank you" for Pittrek, you must have had a lot of work with all those uploads.
At second a brief analysis of your Hammy 79 version:
Yesterday I completed the download of the Kampuchea show and have listened to it twice so far. You should know that it's my favourite Queen show (like it is for many others) and I have listened to my previous 2 versions at least a hundred times.
I is clear that this version is the best so far, and that it was a good idea to create a matrix of all the different sources. It's a pity that the songs with the worst sound quality (WWRY fast, especially) couldn't be improved though – it guess there was a live mix problem, since the guitar is much too quiet and the bass is a bit blurry.
But – there always has to be a "but" – I'm still not perfectly satisfied with this version. Please don't take this as criticism, I appreciate your work very much, Pittrek, and I know that you're no professional sound engineer. I'm none either, so my comments just represent my personal opinion. But of course they are also meant to encourage any pro or skilled amateur to improve this great version even more.
One thing that might be improved are the transitions between songs where different sources were used. They are very well audible, not only because the sound character changes (just naturally), but also because there's sometimes a slight break, as if the parts don't fit exactly. Maybe an improved crossfade could do miracles.
At least in 2 songs (DSMN and the beginning of LOML) there's a strange reverb that I'd put down to a wrong alignment of the different sources. I know that it is very difficult to keep everything perfectly aligned, especially when the original tapes ran at unstable speeds while being transferred. That's real professional work, of course. Maybe it would have been wiser to do without the second source or to keep the level lower at these problematic places.
But in spite of everything said above, this is the best version of this show for today, and it makes any other version obsolete.
... I'll be back again before it's time for sunny-down ...
