They put out their self-titled debut album the next year, which included the song "A Casa Caiu." The track became widely known, capturing a certain mood of the time. Their second album, "Alto Fluxo," came out in 1987. The band played energetic live shows and became a familiar presence on TV and radio during that period. They released a third album, "Astronomia Popular," in 1989 before disbanding in 1990. After Zebillin ended, Marcos Valle continued with a solo career.
