While these African-American string-band aficionados' irresistibly charming 2010 debut includes lively traditionals like "Cornbread and Butterbeans," their revivalist tendencies have evolved into more personal statements. Founding banjoist/singer Rhiannon Giddens displays a passion for country on her 2015 solo debut, which features a solid take on Dolly Parton's "Don't Let It Trouble Your Mind." The Drops subsequently took a political turn with both the hard-times ballad "Leaving Eden" and Giddens' brassy solo version of Pops Staples' liberation-gospel standard, "Freedom Highway."
