Summernights (1990) came from a bar I frequently

visited with friends. One of the regulars at the bar posed

a question rather loudly: ‘Do you know the shape of the

night?’ After ignoring a few obscene and nonsensical

answers he told us himself: ‘The shape of the night is a

cone.’ The shadow of the earth is of course a cone, but

calling it ‘the shape of the night’ was, to me, a profound

observation that stayed with me until, decades later,

I made a piece based on this.
