Nightclubs are becoming more popular than concerts and shows in Las Vegas, according to local ticket broker Ken Solky, who is also president of the National Association of Ticket Brokers. Solky recently told the Las Vegas Review-Journal that while certain big draws such as Celine Dion, Lady Gaga and Elton John remain popular, a lot of other shows, concerts and boxing matches have been disappointments, like a recent performance by Britney Spears and a fight between Amir Khan and Zab Judah. "The crowd that's coming here from spring to the end of summer, so far, is here to party in the club, party in the pool and drink, which includes the DJ deal," Solky said.
