[2] In 2019 he formed Les Limones, a family-oriented music band; Martínez plays the cajón peruano, the bombo legüero, timbaletas and bongos.
As part of the marketing strategy devised by FWTV, Martínez starred in a series of satirical videos ahead of the 2015 general election in the role of "Omar Obaca", a fake presidential candidate whose name and presentation parodied Barack Obama.
Obaca's popularity led the marketing company to double down by plastering fake campaign posters across the Greater Buenos Aires with comedic slogans, such as "vote black" (a quip on blank vote, as "blank" and "white" are the same word in Spanish), and calling on voters to back "the first black president of Argentina".
Martínez, on the other hand, defended his character contending that there were "much worse things" than a black politician in a suit who is broadly admired.
[6][7] Martínez continued to perform as Obaca after the elections, such as during Barack Obama's 2016 state visit to Argentina, when he stood in vigil outside Ezeiza Airport waiting for the US president to arrive.
