cam footage from 9 June. After U2's performance was filmed in Boston for the video release, producer Steve Lillywhite and engineer John Harris (of Effanel Music) created stereo and 5.1 surround sound mixes of the concert. The band could not be physically present to give feedback, as they were still on tour, so guitarist the Edge collaborated remotely with Lillywhite and Harris on the mixes. Using technology provided by Rocket Network, the Edge used an interface at Abbey Road Studios to access the mixes on secure servers and make edits in Pro Tools, which were then shared with Lillywhite and Harris. Release and promotion Part of U2's 6 June concert in Boston was televised that day on NBC during halftime of Game 1 of the 2001 NBA Finals; the network aired a live performance of "Where the Streets Have No Name", followed by a pre-recorded performance of "Elevation" from earlier. The video was released on a two-disc DVD set for a list price of US$32.98 and on VHS for US$19.98. In North America, Interscope Records agreed to give retailer Best Buy a two-week exclusivity window in which to sell the video starting 20 November 2001, before offering it to other retailers on 4 December. Sources told Billboard that the promotion was proposed to the band by a consortium of media partners consisting of DirecTV, VH1, Clear Channel Communications, and Best Buy, who agreed to commit US$10 million to market the video. The deal as originally proposed would have given Best Buy the exclusive rights to sell the video, but Interscope was concerned with how other retailers would react and negotiated a reduced exclusivity. The concert was televised on VH1 on 24 November and on DirecTV on 2 December. Several radio stations in Boston, including WBCN-FM (104.1), WBMX-FM (98.5), WBOS-FM (92.9), and WZLX-FM (100.7), broadcast the concert to coincide with its November airing on VH1. Many retailers reacted negatively to the two-week exclusivity given to Best Buy. Glen Ward, the president of North American operations for Virgin Entertainment Group, said Interscope was acting irresponsibly, stating, "They should be helping us to stimulate the consumer, instead of restricting our business and kowtowing to creamers". Ward said his chain would not sell Elevation 2001 and would not feature the band's most recent album All That You Can't Leave Behind in any price-and-position promotions. Smaller merchants said they were considering collaborating with each other
