An LA Observed informant who has been at most Hollywood Bowl events this summer reports that Keanu Reeves showed up early on his motorcycle for last night's Radiohead show and asked to wait inside the west gate, near the close-in boxes and out of sight of gawkers. Among the others who came in through that way were Mary-Kate Olsen, Tobey Maguire, Juliette Lewis, Rosanna Arquette and Garry Shandling. Justin Timberlake and Jessica Biel, Rainn Wilson and Dominic Monaghan were also spotted in the Bowl. The LAT's Ann Powers reviewed Sunday's show.
