Architect Daniel Libeskind listens to a solid block of uninterrupted music in the morning to start his day.nbsp; "Itrsquo;s not something of a luxury, itrsquo;s almost a necessity.nbsp; And itrsquo;s not background," says Libeskind.nbsp; "I donrsquo;t do it as the hustle bustle of domestic life and in the background therersquo;s music, I sit down, when I have time, and mostly I do have time early in the morning, just to listen to a piece of music."nbsp; In his downtown New York studio, Libeskind and I listened to the music that focuses him for the day, the music that "furnishes his mind":nbsp; Cab Calloway doing "St. Louis Blues, " Glenn Gould playing the Well-Tempered Clavier, the 20th organ music of Olivier Messiaen, and the free jazz improvisations of pianist Keith Tippett.

"Itrsquo;s the equivalent for the soul what running and jogging would be for the body.nbsp; Itrsquo;s not for the body, itrsquo;s for the soul.nbsp; But the soul also needs to be fed.nbsp; Otherwise itrsquo;s empty.nbsp; And that music, when you fill your mind with it, your mind isnrsquo;t empty during the day.nbsp; Itrsquo;s furnished."
