 A series of short trailers for " Trampoline " , getting gradually longer in length , teased different sections of the instrumental and music video . Each teaser features the Demonstration insignia , which is a horizontal red stripe going through the centre of the artwork . The first teaser was five seconds long and simply a synth and sub drop . The second is seventeen seconds long and shows a hanging microphone , accompanied by slightly more of the track . The third shows a hooded Tinie , accompanied by a different section of the track . At the end Tinie says " yeah " . The fourth and final trailer was released a day prior to the premiere of the track , and includes part of the chorus . It shows Tinie walking up to the camera and grinning . The album artwork and artwork for each of the singles feature the red stripe , and even the colour two @-@ tone vinyl has a red stripe going across it . The stripe also features on the physical disc . Tinie teamed up with Warner Music Group to develop the Tinie Tempah : Rap Demonstration app for the iTunes Store , released on 5 February 2014 . The app uses recordings of Tempah 's mouth rapping the album in its entirety , and the idea is that you can rap along to it .
