If you haven’t heard of the Ironics, you will recognize their members and know this will be an exceptional show. This is a special band built around the music of Earl and Mari Robbins, fine songwriters and singers, and the wonderful people who have produced several stellar shows at Heartwood (Don David, Pasture Prime, Cassie Keenum). For the past two years, Mari and Earl have been holed up at Heartwood producing a great album with Bob McPeek and a cast of great players. Joining Earl (guitar and vocals), Mari (vocals), and Bob (many guitars and vocals) will be Imposters’ guitarist Michael Derry and singer Samara Golabuk, who dazzled us with her great voice at the Joni Mitchell Both Sides Now concert in November. The rhythm section will be flawlessly handled by none other than Rob Rothschild (Imposters, Relics, Don David Band, Moondancer, and more bands than he can shake a stick at) and bassist Richard Bassil (who has played with a million Gainesville bands from Jane Yii onward and once played with the Jefferson Airplane’s Marty Balin). The Ironics’ secret weapon (no irony here) is ace keyboardist and singer, Josh Pearsaul.
