Born in 1862, Idylle de Printemps composed in 1889. Delius began serious composition at a relatively advanced age. His music was largely unknown and unperformed until the early 20th century.
Bernard Hermann was said to have been inspired by Wagner's liebestrode from Tristan & Isolde when composing the love score for. Vertigo. But listen closely. Delius may well have been his inspiration here.
