Right On John is one man - John McColley. He's a one-man band, too. There's something so goddamn appealing about a one-man band, as Right On John is in the classical sense. He utilizes no looping contraptions. A man and a cavalcade of instruments is what he delivers. He takes his tools - a cigar-box guitar, a harmonica, a drum, a fiddle - and crafts tight Steve Earle-esque porch-jam ruminations with a subversive bent. Hints of punk-rock attitude gleam at the corners, making the country a little noisier and the bluegrass a little dirtier. Ultimately, the slight gimmick of watching one man juggle several instruments at a time is the dominant reason to see a Right On John show. But if the songs don't work, the gimmick gets old quick - a problem Right On John needn't worry about.
