ドナウエッシンゲン音楽祭
"Atmosphères" was commissioned in 1961 by the Southwest German Radio and had its world premiere on 22 October 1961 by Hans Rosbaud conducting the SWF Symphony Orchestra at the Donaueschingen Festival. Ligeti dedicated the piece to the memory of Mátyás Seiber, a fellow Hungarian-born composer who had been killed in a car crash the previous year. The SWF recorded this performance for broadcast, and this recording has been released commercially on CD several times. Paul Griffiths writes that this performance made Ligeti a "talking point". Ligeti says that after this and his earlier piece "Apparitions", he "became famous".
