In January 1969, the Swedish pianist Ingrid Lindgren, who was studying at the Royal Swedish Academy of Music at the time, recorded three of Morton Feldman's piano pieces together with the composer. She recalls:"The recordings were made when Feldman was giving a course as a guest teacher at the Music School of Swedish National Radio based at Edsberg Castle to the north of Stockholm. Some of us pianists from the Music Academy were invited to take part. At the same time, the Swedish photographer and film maker, Pål-Nils Nilsson, was making a film about Edsberg which was broadcast on Swedish TV. In one sequence, Feldman and myself were filmed as I played some Mozart and we discussed the music. After that, it was decided at short notice by Sven-Erik Bäck (composer and Director of Studies at Edsberg) and Swedish Radio that Feldman should make a radio recording together with me. Pål-Nils Nilsson took some stills of us while rehearsing in the studio, two of which are included in the book Svenska musikperspektiv, published by the Royal Swedish Academy of Music in 1971."
"A small detail: I was wearing a skirt and bright red, thick woollen socks during the recording. Feldman put on a big smile when he noticed this and looked more at my socks than in the score! But I'd like to make it clear that he was a perfect gentleman when we spent time together. He was never hitting on me or making inappropriate remarks. He would call me whenever he was in Stockholm and always asked the same question: "Hello Ingrid, are you married or divorced?" He had an great interest in antiques, and we would visit every antique shop in the Old Town in Stockholm. When we sat down for a meal, he would tell me about his composer friends in New York; Cage, Brown and Wolff. He said they never discussed music, but instead the other arts, preferably painting."
Ingrid Lindgren is one of Sweden's most versatile pianists, accomplished as a soloist as well as an accompanist, chamber music player and orchestral pianist. Though her repertoire includes the music of the old masters, she has always taken a special interest in contemporary music. She was responsible for introducing the music of Ruth Crawford Seeger and Galina Ustvolskaya in Sweden. She studied with some of the leading Swedish teachers, including Sven Brandel, Gunnar Hallhagen and Greta Erikson, as well as with international artists like Aloys Kontarsky, Morton Feldman, Gerald Moore and Erik Werba. She is thoroughly acquainted with the Scandinavian piano repertoire and several Swedish composers, including Sven-David Sandström, Jan Sandström and Daniel Börtz, have dedicated works to her. In addition, she has given first performances of pieces by a dozen other Swedish composers. Her series of recordings of the piano music of Emil Sjögren has received the highest critical acclaim. She has given solo recitals in Paris and Washington D.C. among many other appearances outside Sweden. Along with her extensive pianistic activities, Ingrid Lindgren has been involved for an equally long time in the administration of Swedish musical life. She is currently vice chair of the Emil Sjögren Society.
