a strong supporter of the Tibetan independence ever since. 1967–1974: Minimalism: From Strung Out to Music in 12 Parts Shortly after arriving in New York City in March 1967, Glass attended a performance of works by Steve Reich (including the ground-breaking minimalist piece Piano Phase), which left a deep impression on him; he simplified his style and turned to a radical "consonant vocabulary". Finding little sympathy from traditional performers and performance spaces, Glass eventually formed an ensemble with fellow ex-student Jon Gibson, and others, and began performing mainly in art galleries and studio lofts of SoHo. The visual artist Richard Serra provided Glass with Gallery contacts, while both collaborated on various sculptures, films and installations; from 1971 to 1974, he was Serra's regular studio assistant. Between summer of 1967 and the end of 1968, Glass composed nine works, including Strung Out (for amplified solo violin, composed in summer of 1967), Gradus (for solo saxophone, 1968), Music in the Shape of a Square (for two flutes, composed in May 1968, an homage to Erik Satie), How Now (for solo piano, 1968) and 1+1 (for amplified tabletop, November 1968) which were "clearly designed to experiment more fully with his new-found minimalist approach". The first concert of Glass's new music was at Jonas Mekas's Film-Makers Cinemathèque (Anthology Film Archives) in September 1968. This concert included the first work of this series with Strung Out (performed by the violinist Pixley-Rothschild) and Music in the Shape of a Square (performed by Glass and Gibson). The musical scores were tacked on the wall, and the performers had to move while playing. Glass's new works met with a very enthusiastic response by the audience which consisted mainly of visual and performance artists who were highly sympathetic to Glass's reductive approach. Apart from his music career, Glass had a moving company with his cousin, the sculptor Jene Highstein, and also worked as a plumber and cab driver (during 1973 to 1978). He recounts installing a dishwasher and looking up from his work to see an astonished Robert Hughes, Time magazine's art critic, staring at him. During this time, he made friends with other New York-based artists such as Sol LeWitt, Nancy Graves, Michael Snow, Bruce Nauman, Laurie Anderson, and Chuck Close (who created a now-famous portrait of Glass). (Glass returned the compliment in 2005 with A Musical Portrait of Chuck Close for piano.) With 1+1 and Two Pages
