Colón "makes the relation between diaspora and Caribbean homeland the central theme of his work," particularly in his 1971 Christmas album, Asalto Navideño. The lyrics and music of the songs on this album "enact the diaspora addressing the island culture in a complex, loving but at the same time mildly challenging way." He went on to have many successful collaborations with other salsa musicians and singers, such as Ismael Miranda, Celia Cruz, Soledad Bravo, and singer-songwriter Rubén Blades.

Because of the great success of his last tour, Colón will continue "Rumba Del Siglo 2019" (Jam of the Century 2019). Politics Colón campaigned, and later became a special assistant and spokesperson for, New York City Mayor David Dinkins from 1989 to 1993. In 1994, in his first political run, Colón
