During the fall of 1963, Ashbery became acquainted with Andy Warhol at a scheduled poetry reading at the Literary Theatre in New York. He had previously written favorable reviews of Warhol's art. That same year he reviewed Warhol's "Flowers" exhibition at Galerie Ileana Sonnabend in Paris, describing Warhol's visit to Paris as "the biggest transatlantic fuss since Oscar Wilde brought culture to Buffalo in the nineties". Ashbery returned to New York near the end of 1965 and was welcomed with a large party at the Factory. He became close friends with poet Gerard Malanga, Warhol's assistant, on whom he had an important influence as a poet. In 1967 his poem "Europe" was used as the central text in Eric Salzman's "Foxes and Hedgehogs" as part of the "New Image of Sound" series at Hunter College, conducted by Dennis Russell Davies. When the poet sent Salzman "Three Madrigals" in 1968, the composer featured them in the seminal "Nude Paper Sermon", released by Nonesuch Records in 1989.
