Singer-songwriter Peter Case is one of the great modern-day troubadours: a complex, original lyricist who fuses many of the great American musical styles-blues, rock 'n' roll, country, soul, R&B, folk-Case is considered one of the most dynamic solo artists around. Case has recorded 8 CDs as a solo artist, been nominated for a Grammy, and received Album of the Year honors from the New York Times. Case's early days in the 80's as lead singer and writer for the terrific rock band The Plimsouls earned him much recognition, but it's through his work as a solo act over the last two decades that Case has staked out his place in music history as true original. Case was recently showcased in the feature film "Troubadour Blues".   $20
