In particular, he frequently incorporated patterns from nengón, a precursor to the son, in his compositions, influenced by tresero Chito Latamblé who played with him for years.
Despite being rooted in son traditions, Martínez's compositions also incorporated classical and jazz influences, giving rise a very innovative approach.
[7] In 1994, Raúl Planas and Radio Progreso announcer Eduardo Rosillo approached retired pianist Rubén González with the idea of recording new versions of ten songs composed by Martínez.
[11] The resulting album, Son inconcluso, featured a full band including bassist Orlando "Cachaíto" López and tresero Arturo "Alambre Dulce" Harvey (ex-Conjunto Chappottín),[12] among others, and was released in 1999 by EGREM.
Among the artists that recorded Martínez's compositions as part of the project were Pedro Lugo "El Nene", Mayito Rivera, Issac Delgado and Paulito FG.
[14] The resulting album, titled Esto sí se llama querer, was released through Cuban label Unicornio in 2002, receiving favourable reviews.
