Dutch DJ/producer Tiësto’s second studio album, “Just Be,” debuted at No. 3 on the Billboard Top Electronic Albums chart in June. A couple of months later, in front of a global audience of a few billion, he performed at the opening ceremony of the Olympic Games in Athens. The beat-mixed “Parade of the Athletes”—eight new originals and four remixes of classic Tiësto tracks—spotlights the primarily pulsating and wholly instrumental trance music he played during the event. And while a handful of tracks are thrilling victories (“Ancient History,” “Euphoria,” “Athena”), others border on sameness. More sonic variety would have made this parade worthy of the gold.—MP
