Premise: The Tractors are an American country rock band composed of a loosely associated group of musicians, headed by guitarist Steve Ripley. Under the band's original lineup, The Tractors was signed to Arista Records in 1994, releasing their self-titled debut album that year; the album only produced one Top 40 hit on the "Billboard" country charts. To date, the band has followed up with five more albums.
