From their early post-punk and new wave roots (“Tédio”) to their latter-day pop incarnation (“Quando Eu Te Encontrar”), Biquini Cavadão have defined and redefined the sound of Brazilian rock. Hailing from Rio de Janeiro, the four-piece has managed to stay relevant since the mid-’80s, thanks to their willingness to adapt and experiment without losing their indubitable tunefulness. Take, for instance, the rousing piano balladry of “Timidez” and the driving hip-hop beats that underscore “Janaína”—all buoyed by lead singer Bruno Gouveia’s unmistakable baritone.
