I've also wondered, why LSO Live is so unsystematic. Perhaps they haven't been pleased with the quality of some recordings? Who knows, I don't. Very odd. That listing doesn't seem to be complete. It's after all a 8+4 disc collection. They have quite a nice series of Sir Colin's work: http://lso.co.uk/sir-colin-davis-recordings My first thought was that finally they put together the works of Elgar, Nielsen and Sibelius. No such luck, I'm afraid.
