Tributosaurus, the self-described "Jurassic beast of multiple musical faces," morphs every month into a new rock group, delivering ambitious note-for-note covers of hits and album tracks by some of the biggest recording artists of all time. These experts will tackle any song, embracing complexity by enlisting whatever pinch hitters are needed (extra synth players to recreate Genesis, for example). After years of consistently excellent incarnations, Tributosaurus stand as a pillar of Chicago's live-music scene; tonight, they launch their Signature Series with a set as art-rock tastemakers XTC.
