Legal woes behind them, the Campbell Brothers look onward
Seven years ago, the Campbell Brothers released an album that shed light not only on the band, but an entire subgenre of gospel music. The Campbells play sacred steel, a strain of gospel driven by lap- and pedal-steel guitars for a sound that’s hardly sanctimonious. If you didn’t pay attention to the lyrics, you might guess you’re listening to a contemporary funk or R&B band. The group performs at the Museum of Fine Arts on Wednesday.
