Tiesto strikes an unintentional superhero pose on the cover, which only makes sense: the Olympian DJ has been the world's king of trance for so long, the stance must be second nature. But while the thumping rhythms and whooshing effects here stem from his stadium-rave history, these songs set their phasers on "pop." And why not? After Lady Gaga, listeners are primed for Tiesto's brand of bright, mega-melodic, hyper-produced anthems. Flush with contributions from Nelly Furtado, Tegan & Sara and even Bloc Party's Kele Okereke, Kaleidoscope's caped crusade aims straight for the airwaves.
