Unusually for Warner (and music videos in general) “Live By Request” features not only a Dolby Digital 2.0 audio track but also a choice of Dolby Digital or DTS 5.1 tracks. Putting the three tracks in order of quality I'd have to start with the vanilla 2.0 soundtrack. There's nothing particularly wrong with it but compared with the two multi-channel tracks it sounds rather flat and seems to lack the dynamics and “live” atmosphere offered by the 5.1 tracks. Next would be the Dolby Digital 5.1 track with the DTS track just pipping it to the post. As with Warners release of “Travis: Live at the palace” the mix here does offer more than a simple music/audience split. Whilst the rear channels do carry ambient effects (including the audience getting involved in the show), we also have music mixed in, as well as a little reverb, adding to the music's presence. It's here that the DTS track just edges past the Dolby Digital one with a slightly wider (and more believable) sound stage, but there's very, very little in it. Very good all round.
