Answer by taking a quote from the following article:

James Stanley Brakhage ( BRAK-@j; January 14, 1933 - March 9, 2003), better known as Stan Brakhage, was an American non-narrative filmmaker. He is considered to be one of the most important figures in 20th-century experimental film. Over the course of five decades, Brakhage created a large and diverse body of work, exploring a variety of formats, approaches and techniques that included handheld camerawork, painting directly onto celluloid, fast cutting, in-camera editing, scratching on film, collage film and the use of multiple exposures. Interested in mythology and inspired by music, poetry, and visual phenomena, Brakhage sought to reveal the universal in the particular, exploring themes of birth, mortality, sexuality, and innocence.

When Brakhage's early films had been exhibited in the 1950s, they had often been met with derision, but in the early 1960s Brakhage began to receive recognition in exhibitions and film publications, including Film Culture, which gave awards to several of his films, including The Dead, in 1962. The award statement, written by Jonas Mekas, a critic who would later become an influential experimental filmmaker in his own right, cited Brakhage for bringing to cinema "an intelligence and subtlety that is usually the province of the older arts." Writer/critic Guy Davenport, an ardent admirer of Brakhage, invited him to the University of Kentucky in March 1964 and tried to get him a residency there.  From 1961 to 1964, Brakhage worked on a series of 5 films known as the Dog Star Man cycle. The Brakhages moved to Lump Gulch, Colorado in 1964, though Brakhage continued to make regular visits to New York. During one of those visits, the 16mm film equipment he had been using was stolen. Brakhage couldn't afford to replace it, instead opting to buy cheaper 8mm film equipment. He soon began working in the format, producing a 30-part cycle of 8mm films known as the Songs from 1964 to 1969. The Songs include one of Brakhage's most acclaimed films, 23rd Psalm Branch, a response to the Vietnam War and its presentation in the mass media.  Brakhage began teaching film history and aesthetics at the School of the Art Institute of Chicago in 1969, commuting from his home in Colorado.

What else did he receive attention for n the early 60s?
From 1961 to 1964, Brakhage worked on a series of 5 films known as the Dog Star Man cycle.
