Grammy awar winning superstar group Intocable (Untouchable) is a Tejano/Norteño musical group from Zapata, Texas that was started by friends Ricky Muñoz and René Martínez in the early 90's. Within a couple years as a band, Intocable had already risen to the top of the Tejano and Norteño fields with a musical signature that had fused Tejano's robust conjunto and Norteño folk rhythms with a pop balladry. Currently, Intocable could very well be the most influential group in Tejano, and their tough Tejano/Norteño fusion has become the blueprint for dozens of Tex-Mex groups. The group's strengths, which include romantic hooky melodies, and tight instrumentation and vocal harmony is consistently being imitated by a list of other great Tejano and Norteño groups. This list includes groups such as Imán, Duelo, Costumbre, Solido, Estruendo, Intenso, and Zinzero among others.
