features songs in Spanish and English combining the genres of salsa and swing, Blades explained in the album notes that with the album he wanted to further the connections between the two genres, citing as example of connections the numerous collaborations between American and Latin American musicians throughout the years like Mario Bauzá with Dizzy Gillespie and Machito with Charlie Parker, he wrote that "with this album I try to continue this relationship, proving that art does not have nationality but represents a spirit that transcends races, geographies and languages", he continued by saying that one of his goals with the album was to "eliminate the stereotype that affirms that we are conditioned to only exist artistically within specific boundaries according to our nationality", hence the collaboration with a Panamanian band as a Panamanian himself to explore genres from different parts of Latin America and United States.
