It was a tough blow for rock. As a group, Virus survived and soldiered on into the 1990s as a more adult pop-rock outfit than the outrageous yet influential 1980s band that helped define the sound of "techno-pop". Three major trends defined the Argentine rock of the end of the 1980s. The first trend was the consolidation of the Argentine Invasion bands into somewhat more mature rock groups. Some began to experiment with world music in the last two years of the 1980s. For example, Charly García got together with his old Serú Girán partner Pedro Aznar and recorded "Tango", whose name accurately suggests the style of the album. Before Federico Moura's death, Virus had also begun turning to Brazilian music for their album Superficies de Placer. In general the mood of the music got darker echoing a deteriorated economic climate. A second was the rise of "Tropical" rock, and the explosion of local Reggae bands in Argentina seemingly out of nowhere in 1987. While Argentine rock was triumphant internationally, Argentina was caught in a reggae-mania: in the summer of that year arose Los Pericos, Los Cafres, La Zimbabwe, and Jafran, among many other smaller outfits. But it was a fad, and only Los Pericos would sustain and grow their careers once the fancy faded (Los Cafres would be mildly successful starting in 1994). A band that was not a fad was Los Auténticos Decadentes, who would become a hugely popular ska-Latin pop and ballad group. They along with Los Pericos and Los Fabulosos Cadillacs would be leaders in the tropical rock scene of ska, reggae and Latin music. The third trend came about partly as a result of the first: many rock fans did not approve of the commercialism and experimentation of the A-bands, and increasingly looked underground for a more confrontational guitar-led rock. Among them: Todos Tus Muertos, Don Cornelio y La Zona (later Los Visitantes), Los Brujos, Babasónicos, Los Siete Delfines, Massacre Palestina. All of them would be part of the "Nuevo Rock" ("New Rock") explosion of the early 1990s. In heavy metal, the already mentioned Rata Blanca dominated popular tastes, specially in other Latin American countries, along with Hermética, JAF, and Horcas (the last two more domestic), in a very healthy scene for a style that never was overwhelmingly crowded in Argentine rock. An important band in the metal underground was Nepal, one of the pioneering
