The popularity of “Locuras Contigo” soon spilled outside Uruguay. In February 2015, the group released its second single “Yo También” (Me Too).
Rombai's success left fans clamoring for more material, which made Rombai one of Uruguay's most successful musical acts.
In 2016, the group invited the alluring Argentine singer Emilia Mernes to join. Hitting the festival circuit, Rombai performed in cities and towns across Uruguay, Argentina, Chile, Paraguay, Bolivia, Ecuador, Peru and Brazil.
In 2018, the group signed a management deal with WK Entertainment, whose clients include Carlos Vives, Maluma, Wisin, CNCO and many more. Launching a tour in Chile, the group concluded things on a high note with a crowd of over 120,000 in Talca. It was also the last group performance with Emilia Mernes, who launched a solo career.
Great news for the band continued, as it signed with Sony Music US Latin. The 2018 Rombai features the new member Megumi Bowles (Megu), from Bolivia.
