Los Van Van is one of the most important bands in the history of the 20th century. Though 1990s Cuba was pervaded by groups that mixed folkloric and traditional music with the musical trends of the day, and the beginning of the 21st century saw that process go even further, in the 1960s and '70s that Latino fusion sensibility was scarce at best. There were primarily two Cuban groups experimenting with mixing pop, funk, rock, and soul with their native traditions.
