'Live music is another way to keep people at the casinos.' 'Today, the musical acts playing at casinos are established names that we've known for years,' Fiorenza said. (Casinos in the region like Horseshoe and Maryland Live typically book lesser-known acts like regional cover bands and tribute groups trading in nostalgia.) Casinos and resorts using A-list talent to appeal to customers is nothing new in a market like Las Vegas, but it's a more recent trend in states like Maryland and Pennsylvania, said David Fiorenza, who teaches the economics of the entertainment industry at Villanova University School of Business.
