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.
Hypothesis: Since their foundation, most of the band's original members have moved on to separate projects, although they often collaborate with frontman Ripley on The Tractors' more recent recordings. Ripley is the only official member of the group.
