It was said that, following their marriage in 1963, the artist Marian Zazeela, who has died aged 83, and the composer La Monte Young never spent a day apart – each day for them consisting of 33 hours and 36 minutes, thanks to a decision to live their lives according to a calendar in which the 168 hours of the conventional week were divided between five rather than seven days.
The most enduring of their creations was the Dream House at 275 Church Street in downtown New York. There, on almost any day for the past three decades, those who climb the narrow staircase to a room on the third floor have found themselves, after observing a request to remove their shoes and perhaps dropping an optional $5 bill into a donation box, in an environment like no other.
