Adapting the old “If life gives you lemons” adage to the Nashville Flood, ReTune Nashville takes flood-ravaged musical instruments and converts them into art, to raise money to help the many uninsured musicians whose lives were devastated by the disaster. ReTune founder Sheri O'Neal, a Nashville photographer, originally set out to find 10 visual artists who would volunteer their time, and soon wound up with 70. Many of the pieces were donated by road and studio musicians like Brent Mason, Keith Horne, Chris Leuzinger, Michael Spriggs and Tim Marks, most of whom lost their instruments when rehearsal and storage facility Soundcheck became submerged under the raging Cumberland. (Fittingly, the resuscitated Soundcheck is hosting the benefit.) Participating visual artists include Rachel Kice, Marleen De Waele-De Bock, Michael Manly, Heather Lose and Brother Mel, to name a few. If you can't afford to bid on items such as Raul Malo's damaged ax — revived by designer-to-the-stars Manuel (expect some serious bling) — your $35 ticket ($45 day of event) still gets you a performance by country artist Jamie O'Neal (“There Is No Arizona”), Jeremy Lister, Anthony Smith, Kentucky Thunder and Eddy Raven.
