"Ilusiones Perdidas" is not a composition by Ignacio Cervantes; instead, it's a famous work by Cuban composer Ernesto Lecuona. Ignacio Cervantes, on the other hand, was a Cuban composer as well, known for his contributions to the Cuban classical music genre, particularly his habaneras. One of his most famous compositions is "Danzas Cubanas," a collection of piano pieces that showcase his Cuban roots. Cervantes lived from 1847 to 1905 and left a lasting impact on the music scene in Cuba.
