Michael Lawrence Marrow (August 2, 1955 – December 12, 2019), known as PHASE 2 and Lonny Wood, was an American aerosol paint artist based in New York City. Mostly active in the 1970s, Phase 2 is generally credited with originating the "bubble letter" style of aerosol writing, also known as "softies". He was also influential in the early hip-hop scene.

He was from the Bronx, and attended DeWitt Clinton High School along with a number of other early aerosol artists. Many famous transit writers of the early 1970s would meet at a doughnut shop across from the school called the Coffee Shop before heading down to the subway station at 149th Street and Grand Concourse to watch tagged trains on the IRT line pass by. He was mentored in the art of style writing by his friend and neighbour Thomas Lee aka Lee 163rd, one of the early pioneers of the movement in the Bronx.
