When the inimitable David Bromberg puts on a show, anything could happen, especially when you add top-notch singers and a rockin’ big band. See the fireworks when the guitar virtuoso returns to The Grand Opera House in Wilmington May 5. Mandolins, fiddles, horns and, of course, guitars cover several genres, including blues, folk and bluegrass. See why the 2008 Grammy-nominated Bromberg is a legend.
