A smooth sextet that delivers modern Americana and retro-country, Boot Juice can go from graceful to gritty at the drop of a cowboy hat. The band shows its acoustic strength on “Speaking in Tones,” a relaxed story-song with a soulful electric guitar solo that foreshadows what’s in store. That guitar brings a tasty growl to “Save My Soul,” a downhome blues-rocker that has great harmonica fills, then shifts into high gear for a memorable guitar solo. “Tempting Fate” displays the band’s ability to deliver a countrified throwback tune. This is a tight unit of above-average musicians who could bring excitement to a club stage. On these recordings, their vocals are not as consistent as they could be.
