In May 1648 he went to Mexico City, where he was hired by the cathedral organist Fabián Ximeno, who had heard López Capillas on a visit to the Puebla cathedral and been impressed with his talent. He was chapelmaster of Mexico City Cathedral from 21 April 1654, until his death. He was the most prolific composer of Baroque masses in Mexico.
