The Main Street Live summer concert series continues this Friday night with country music from the Alvarado Road Show.The band is out of Nashville and features a brother duo with Cleve Clark and A.J. Clark. The brothers create and perform rootsy American music about life, love and relationships.The band’s biography says, “When you witness one of their performances, they will paint a colorful picture with words, notes and heart through warm blends of harmony that will move and forever change the way you experience music.” The guys frequently tell stories of the days they played in a chicken coop and in front of a laundry mat from years ago, and of the road that led them to perform at the Grand Ole Opry.
