After a few years of playing percussion in samba bands at S.O.B.'s and other venues. Polar landed in hip hop which combined his interests in grooves, samples and wordplay into one form. He and rapper D.A.V. became Medicine Crew. In the aftermath of 9/11, Polar was asked to do a remix of Nile Rodgers' We Are Family Project released on a compilation by Tommy Boy Records. His experience of 9/11 which was perpetrated in his neighborhood led to a collaboration with multi-platinum Pakistan rock band Junoon resulting in their hit song 'No More'. John Hollander has choreographed four Polarity/1 compositions for New York's Battery Dance Company's fall season opening in November 2006 and has been touring extensively with the piece. In 2008, he scored "The Other Side" for the Quorum Ballet from Lisbon Portugal. P/1's new collaboration, Koko Dozo, released their first album Illegal Space Aliens in February 2008.
