"A small, unvarnished trove of American music…. Williams is a songster at heart, still in thrall to the rich, cross-quilted music he heard on the radio in his youth. Which is why 'Blues Highway' isn't all that blue; it's dotted with little rest stops where Williams puts aside tunes associated with Blind Boy Fuller (a guitar and harp boogie version of 'Step It Up and Go'), Big Bill Broonzy (a soulful solo version of 'Key to the Highway') and other blues artists long enough to indulge a taste for vintage pop ballads, jazz favorites and country novelties. Nothing proves more engagingly corny than 'Hey, Bartender, There's a Big Bug in My Beer,' which features a delightful cameo by guitarist Eddie Pennington…. With Summerour's rhythms and responsive riffs, the duo evokes the blueprint guitar-and-harp sound of Brownie McGhee and Sonny Terry."—Washington Post
