Bryden Thomson had a history with Nielsen's Four Temperaments, having performed it on a radio broadcast with the BBC National Orchestra of Wales that has been released on CD. His performance with the Royal Scottish National is tremendous. It conveys immense authority and is played with exceptional discipline. The highlight is probably the slow, or melancholic, movement, which proceeds with an almost unbearable tension. The outer movements have great thrust and momentum. By comparison, the performance of the First Symphony is a bit of a letdown. It certainly is very good, and the wonderful finale is executed with brio, but it just doesn't have the authority of the Second. The sound engineering throughout the CD is excellent, full and well balanced while conveying the real impact of the orchestral sound. The only recordings I can place in the neighborhood of Thomson's Second are LPs by Ole Schmidt and Carl Garaguly.
