Swedish rock band Graveyard have been doing something nifty on YouTube to promote their new album ‘Lights Out’. The Universal-signed act have a teaser video showcasing tracks from the album, with interactivity encouraging fans to find out “what’s behind the cover art of Lights Out?”. That cover art being mainly black, but with elements in the video that, when clicked on, switch to footage of tracks being played in the rehearsal studio. There’s an accompanying Spotify campaign too: a banner ad that looks like a light switch which, when clicked, makes the Spotify desktop app go dark, with a blurred album playlist hidden behind a lamp for fans to turn on. Simple and fun in both cases, and very fitting for the album.
