P. Michael Grego, along with Travis, is a founding member of the noise gospel band ONO from 1980. Grego was born in the Hyde Park neighborhood of Chicago, into a music-loving family - son of a jazz sax player and cousin to Pete Cosey who played with Miles Davis - before being raised in the West Chesterfield neighborhood of Chicago, an area noted for important black musical artists i.e. Mahalia Jackson, Curtis Mayfield, Carl Davis and the Staples Singers. P. Michael is a multi-instrumentalist both trained and self taught, having studied music theory and arrangements under the guidance of noted soul arranger James Mack in Junior College. Grego attended both the School of the Art Institute for film and printmaking and St. Xavier University as a Biology-pre-med student. In 1984, he graduated from Roosevelt University with a Bachelor of Arts in both arts and science. P. Michael continues to hold a keen interest in the sciences.
