Over the years following the composition of "Circus of the Sun", Lax's poetry became more and more stripped down to essentials, concentrating on simplicity and making the most out of the fewest components, a technique common to artistic minimalism. Sometimes these pieces consisted of single words, even single syllables, running page after page. As a consequence his work was perceived as sharing the characteristics of Concrete poetry and was included in Stephen Bann’s defining "Poetry: An International Anthology" (1967) and mentioned in Mary Ellen Solt’s study, "Concrete Poetry: A World View" (1968).
