Their songs Pânico na Zona Sul ("Panic on the Southside") and Tempos Difíceis ("Hard Times") offer a snapshot of favela life with lyrics vividly depicting rampant police brutality, racism, poverty, and crime.

These forums had the dual effect of expanding awareness of Racionas MC's agenda along with their fan base, as residents the favelas in cities across Brazil could relate to the Paulista rap group's experience.

That year the group released their second album, Escolha o Seu Caminho (Choose Your Path), with the notable tracks "Voz Ativa" ("Active Voice") and "Negro Limitado" ("Limited Black Man").

They participated in the National Theatre's Música Negra em Ação (Black Music in Action) project alongside Thaíde e DJ Hum, another prominent São Paulo Hip Hop act.

The album includes several standout tracks including "Fim de Semana no Parque" ("Weekend in the Park"), a lyrical sketch of lowlifes in São Paulo; "Mano na Porta do Bar" ("Man at the Bar Door"), a skillful remix of Curtis Mayfield's "Freddie's Dead"; and the unexpected harmonica and piano jam "Fio da Navalha" ("Razor Edge").
