As a kid, Darius Rucker -- who plays Farmingville's Pennysaver Amphitheater on Saturday -- listened carefully to Kenny Rogers singing "Coward of the County" on the radio. As a 28-year-old, he fronted Hootie & the Blowfish, a band whose impossibly smooth-sounding 1994 pop album "Cracked Rear View" sold more than 16 million copies. At 42, Rucker rediscovered his commercial voice after years of drifting in and out of Hootie -- beginning in 2008, with his hit "Don't Think I Don't Think About It," he began to redefine himself as a country singer, writing songs not with a band but with a rotating group of Nashville session pros.
