Brossé can be counted on for wild cards when conducting the Germanic classics - to him, the great composers are more like colleagues than idols. His views on Beethoven's 5th skewed more toward the classicism from which the symphony came than the Romantic Age it led to. The famous four-note motif wasn't underscored by differentiated tempos. Form framed content. Rarely is the piece played with such clean, non-interruptive lines. One exception was the first movement oboe solo, played by Geoffrey Deemer with the expanse and detail of a Shakespearean soliloquy.

Vaughan Williams wrote 70 years ago for the English oboist Eugene Goosens. The composer might not recognize his work now because the oboe, in America, is music richer in sounds and discursive in range. Deemer exemplifies that revolution. His playing was bold, detailed, and shaped to fill a broad dynamic range. He caught the composer's turn of phrase, made lyrical passages sing with shadings and nuance, and infused the virtuosic passages with color.
