• "One proposal for a mission which would have the right instrumentation is a NASA decadal survey mission ACE - Aerosol Cloud Ecosystems."
• "The instrumentation is heavier now, with trumpet figures and the addition of bass and snare drums lending almost the flavor of an operatic drinking song as the exultant "release" theme, opening with three bright high C-sharps on the violins, piccolo and flute, is answered by a vigorous rising gesture by the cellos and basses fortified by the bass trombone."
