Rob Ickes and Trey Hensley are the Swiss Army Knife of roots music. They’d fit, with their instruments, perhaps not in your pocket but certainly into a compact car. Yet they have more tools at their fingertips than a lot of bigger bands - tools for scintillating grooves, lush harmonies, bluesy yearning, fiery picking, and lyrical beauty. That’s why now, almost a decade into an unexpected journey, Rob and Trey have become a roots country duo with no peers and few if any precedents. They play a free show for WMOT at this week's Finally Friday.
