Rick Griffin (1944 - 1991) was an American artist and one of the leading designers of psychedelic posters in the 1960s. As a contributor to the underground comix movement, his work appeared regularly in Zap Comix. Griffin was closely identified with the Grateful Dead, designing some of their best known posters and record jackets.
It's a Beautiful Day is a band formed in San Francisco, California in 1967 by Matthew Katz, featuring vocalist Pattie Santos along with violinist David LaFlamme and Linda Laflamme on keyboards.
LaFlamme, a former soloist with the Utah Symphony Orchestra, had previously been in the band Orkustra, and unusually, played a five-string violin. Although they were one of the earliest and most important San Francisco bands to emerge from the Summer of Love, It’s a Beautiful Day never quite achieved the success of contemporaries such as The Grateful Dead, Jefferson Airplane and Santana, with whom they had connections. It’s A Beautiful Day created a unique blend of rock, jazz, folk, classical and world beat styles during the seven years the band was officially together.
