In late 1972, Phase 2 first used an early version of the “bubble letter”, a style of writing which would become extremely influential. The puffed-out, marshmallow-like letters drawn by Phase 2 were soon copied by other artists who added their own variations. Phase 2 quickly embellished on his original form, creating and naming dozens of varieties of softies, such as “phasemagorical phantastic” (bubble letters with stars), “bubble cloud”, and “bubble drip”.He described the thrill of tagging subway cars as “impact expressionalism”.He is also credited with having pioneered the use of arrows in graffiti writing around this same time. 

In 1986, Phase 2 became the art director of International Get Hip Times, the first zine about aerosol culture.He was also a b-boy and claimed that his dance crew pioneered the up rock (or “battle rock”) style of dance.

Phase2 died on December 12, 2019 at age 64 in New York City,
