This presentation aims to share with the research community the way we are working in City. We believe our work liberates creative energy for different marketing purposes. Our methods are based on the principles of the very first Brazilian modern art movement (Semana de 22). We call our methodology "Mixologia Cultural" (Cultural Mixology). All of our projects result from a combination of knowledge found in different cultural fields. We would like to share it in CROSS DISCIPLINES EXTRAVAGANZA. We use "Mixologia Cultural" in qualitative projects, in order to separate the superficial deductions, to leave them aside, and to go deeper into what we call the "underground analysis", in order to reach central Insight truths. The methodology has taught us how to isolate fundamental aspects of the behaviour.
