There is a difference between a "rock star" and a "superstar," and Justin Timberlake is a superstar. He'd been a rock star since his years with 'N Sync touring the world and selling millions of albums. But now, in his early 30s, with decades experience performing his own catalog of self-written hit songs, and the swagger that goes along with all that, he is quite obviously in his prime.
The second stop of his 20/20 Experience World Tour went through Glendale's Jobing.com Arena on Saturday night, and he demonstrated what a superstar in their prime is capable of by putting on two-hour musical spectacular complete with choreographed dance numbers, lasers, and a 15-piece band, The Tennessee Kids. He also showed that being a superstar in 2014 is hard work.
