Chris Willman Senior Music Writer and Chief Music Critic Two former hockey players who bailed on Frank Ocean’s Coachella performance after it seemingly became enveloped in chaos Sunday have spoken up about the experience in a podcast. Brothers Dan and Chris Powers say that they and more than a hundred other skaters had a positive experience through a good month of rehearsal in L.A., and even a successful dress rehearsal on the Coachella main stage — only to have Ocean render most of the skaters’ services unnecessary as he scrapped the entire epic ice-capades setup as the festival grounds were filling up. In the first segment of their “Empty Netters” podcast, released Tuesday, the Powers brothers said that there were about 120 skaters who’d been hired for the show and had been rehearsing on a makeshift ice rink at Paramount for weeks — including, they said, several Olympians well-known in the figure skating community, as well as hockey veterans like themselves. In the end, they said, the vast majority of these skating extras were left waiting on buses or in hot tents for hours on the perimeter of the festival grounds as Ocean made the last-minute call to dissemble the ice rink and ditch the planned skate choreography.
