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.
