Final answer:
The pianist who combined a new salsa style with Latin rhythms and jazz harmonies is not specified, but the information describes the evolution of salsa influenced by Cuban culture and other Latin American music and arts, including figures like Torres-Garcia, Figari, Armstrong, Handy, and Soto.
Step-by-step explanation:
The pianist in question who combined a vigorous new salsa style with intricate Latin rhythms, modern jazz harmonies, and imaginative improvisations was not explicitly mentioned in the provided information. However, the Cuban influence on music described relates to the evolution of salsa music with African and Spanish cultural influences, shaping genres like rumba, habanera, son, and timba.
It’s important to recognize that Latin American music has a rich history with prolific artists such as the Uruguayan painter-sculptor Joaquin Torres-Garcia who developed the style called Constructive Universalism, and the Uruguayan artist Pedro Figari who was known for his depictions of local customs in paintings like 'Dancing People: Candomb'.
Meanwhile, jazz music has also been shaped significantly by black musicians during the Harlem Renaissance as described. Artists such as Louis Armstrong, known as a key improviser in jazz history, and W. C. Handy, referred to as 'the Father of the Blues', show the depth of musical innovation stemming from African American communities in the early 20th century. Additionally, other Latin American artists such as Jesús Rafael Soto from Venezuela contributed to the art scene with his involvement in movements like Cubism, Constructivists, and Op Art.
