Two of the most demanding aspects to the Shakira gig that I can think of… is first, the variety of styles in which we, as a band, have to play. We do everything from latin folkloric music, to arabic beats, to rock-&-roll, to super-pop, to piano ballads, to dance and electro stuff. The second is accuracy. It is a challenge to play two-years’ worth of concerts and nail each one of them perfectly. And by perfect, I mean playing the set from top to bottom, nailing the pocket and the click track, and still keep things exciting and fresh on stage.
