Formalized in 2020, the Duet Paty e Leo had actually met much earlier, in 2007 while studying music at college. In addition to seeing each other on campus, they would often run into each other at events where they worked for some of the most important event bands in São Paulo.

​

Always focused on quality, the Duet Paty e Leo has gained experience through performing at over 100 events per year for companies such as JBS, IBM, Bradesco, IBEF, Grande Hotel Senac, Transamerica Hotel, Renaissance Hotel, Copacabana Palace, and others.
