In the build-up to the release of the recordings, the band released a number of web-format clips from the DVD. The full performance of "
Unintended" was added to the band's official website on Christmas Eve, 24 December 2007, dubbed as a "little taste of things to come". On 11 January 2008, a
microsite at www.he-3.mu was announced, featuring a grid of six boxes representing thumbnails of short clips from the DVD. By 17 March, all six clips were filled, featuring short clips from "
Knights of Cydonia", "
Supermassive Black Hole", "
Feeling Good", "
New Born", "Blackout" and the outro riffs of "
Stockholm Syndrome". "Feeling Good" was also released in full to radio and television stations shortly afterwards, although it was not advertised on the official website.
Vue cinemas held special screenings of the concert in
high definition on 11 March 2008 at select cinemas. A special edition of
HAARP was released in addition to the regular CD/DVD, which features additional backstage footage and bonus postcards showing pictures of the three band members. The
HAARP microsite is available for visitors to download
iPod- and
iPod Touch-/
iPhone-formatted videos and mp3s of "Knights of Cydonia", "Supermassive Black Hole", "Unintended" and "
Plug in Baby" featured on the DVD for free. Included is a bonus video of "Micro Cuts" and an mp3 of "Soldier's Poem" from the performance on 16 June. ==Track listing==
