Denver-based bluegrass band Clay Street Unit is hard at work on their upcoming debut album, set for release later this year. Fans of the sextet’s live show will be familiar with their new single “Engine Trouble”, originally recorded by Minnesota’s The Last Revel. This is our first taste of both versions, so we’ve included them for you all below. Clay Street Unit’s version is a little more our speed so we’ll be looking out for more music from them. Check out Clay Street Unit’s upcoming tour dates to see if they’ll be in your town soon.
