Jon Burns, a.k.a. Centaur NoirThe first two tracks of Centaur Noir's Rock the Hall are a study in contrasts. Lead track "Market Street" is a dusty piece of lonesome folk -- guitar, percussion, and a little harmonica under restrained twin vocals, one falsetto and one a hoarse croak.

It's followed by "Only English Spoken," with blunt beats and dominating electronics overwhelming the vocals.

So Centaur Noir, a solo project of Meth & Goats frontman (and Moline resident) Jon Burns, embraces a dual nature. Sometimes the two sides meet -- as on album standout "Ten More Years," in which the lead acoustic guitar is balanced by soft, droning synthesized melodies. But even when they do converge, each song's heartbeat is clearly either folksy or electronic.
