Considered by critics as a "West Coast underground legend," Hassel Smith was an early and influential member of the experimental school of artists that emerged out of post-World War II California. Together with Clyfford Still, Mark Rothko, and Richard Diebenkorn, Smith made his name at the California School of Fine Arts (now the San Francisco Art Institute) and during the early 1960s with successful exhibitions in Europe and on both coasts of the US. While his early paintings are characterized by their wildly vibrant brushstrokes and explosions of color, Smith was equally adept in a more restrained style, turning out geometrically precise abstractions and whimsical studies. As an early burst of fame died out, Smith continued to paint with unwavering energy. The result is a robust and dynamic body of work that reflects Smith's persistent curiosity and, with this volume, a full appreciation of his talent.
