(Carbondale, IL)  —  City leaders in Carbondale are vowing to move ahead with their eclipse rock concert, even after firing their concert promoter. Carbondale City Manager Gary Williams  yesterday said he fired the Arizona-based promotion company because they didn’t land the  “caliber of talent” city leaders expect for the August concert. Carbondale is expected 50-thousand visitors to crowd into town to watch the August 21st solar eclipse, and the city wants to throw a huge party.
