The band Clear Plastic Masks, which drove from Nashville to perform live on stage at yesterday’s Rockabilly Rumble, had never been to Delaware before. Band leader Andrew Katz asked the Market Street audience, “Didn’t Bob Marley live here at one point?” But rockabilly favorites the Tommy Conwell Band, from Philadelphia, and Wilmington’s own The Bullets were in familiar territory, lighting up stages at World Cafe Live’s indoor and outdoor block party concert. In all, 15 bands delivered a terrific mix of rock and folk music over nine hours on three stages at the second annual music festival. “We were really pleased with the high quality bands we attracted this year,” said event organizer Gayle Dillman of Gable Music Ventures. The event, which included food trucks as well as t-shirt and nick back vendors, was co-hosted by World Cafe Live.
