One of the last vertical stripe paintings made before Morris Louis’s death in 1962, Number 4-31 (1962) is a commanding example of an artist at the height of his production, flawlessly synthesizing color and form into a sweeping and hypnotic image. Pulsating with rich atmospheric hues, Sounds in the Summer Night is a testament to Kenneth Noland’s virtuosic exploration of color and an outstanding example from the artist’s acclaimed Target series, a body of work long recognized as one of the seminal achievements of post-war American abstraction. Rendered in exquisite gem-like hues, in the largest scale of the series, and during a seminal year of Josef Albers’s career, Homage to the Square in Green Frames is a superlative example from one of the most iconic series in all of the twentieth century.
