In April 1958 Colin McCahon travelled to the US, responding both to the expansiveness of the American landscape and to the modern American painting that he saw in museums. On his return, his works increased in scale while economising in gesture: the landscape elements of Tomorrow have been reduced to a horizon and lowering sky, with the land bisected by a grey river. He converted his Titirangi garage into a studio, and built an extra bedroom for his children underneath. The studio was gloomy – there was only one small side window for light when the garage door was closed – but it precipitated dozens of new works.
Tomorrow was an unfortunate painting, said McCahon, ‘in that it wouldn’t go right, and I got madder and madder. I hurled a whole lovely quart tin of black Dulux at the board and reconstructed the painting out of the mess.’ The black paint (a commercial flooring paint, mixed with sand) dripped down the surface of the work and ran between wide cracks in the studio floorboards, ruining clothes and bed linen in his sons’ room below. He finally finished the painting in May 1959.
