I've been binge-ing on that recording of late. Larsson does so much with limited but attractive materials. Due to the moderate length of Larsson's melodic phrases, his second symphony stands, in my mind, kind of halfway between Beethoven's 5th, which concatenates short phrases to build up powerful paragraphs of music, and Rimsky's Antar, which concatenates appealing longer tunes (complete musical sentences) without varying them much, except for context and texture (orchestration).
I was quite surprised to hear that Larsson studied with Berg, when most of what I have heard so melodic and rich. His 3rd symphony even has echos of Saint-Saëns
if you listen closely. But there is wonderful melancholy in A Winter's Tale or God In Disguise..and his Violin Concerto is so dissonant it is hard to believe it was penned by the same composer, but it too is a beautiful work
