Gramophone tends to have a bias towards British performances, but I agree Barbirolli’s Mahler 5th is my favorite version
I would agree they were biassed towards British hifi hardware, but I thought they were very even-handed when it came to judging performances. They treated all the great Hungarian conductors living in the USA with much the same respect as the great USA conductors living in Europe!
It is very odd that the British, at least until Elgar, had so few significant composers but by far the biggest concentration of orchestras, particularly in London.
