For the first time, composers Ben Salisbury and Geoff Barrow were able to put together a team of musicians to work together to form a collaborative score for the whole series. The soundtrack consists of songs by Karen O and Beak>, plus an original score by Ben Salisbury & Geoff Barrow + additonal composers The Insects, Simon Ashdown and Yann McCullough. "Because of the size of the HANNA series, we had the opportunity to bring our own team of artists and composers. The Producers had already contacted the amazing Karen O who's song "Anti-Lullaby" formed a theme that was continued throughout the series. It was also great to work with our friends The Insects (Massive Attack co writers Bob Locke & Tim Norfolk), Simon Ashdown & music editor turned composer Yann McCullough" - Geoff Barrow.`Yeah Yeah Yeahs' singer Karen-O's wandering, ominous "Anti-Lullaby" appears on the soundtrack along with her Goth rendition of Smashing Pumpkin's "Bullet With Butterfly Wings", with Beak>'s `Wulfstan II' appropriately closing the album..The score for `HANNA: Season 1' features layers of manipulated organic elements which composer Ben Salisbury describes below -"The score for the series was mainly inspired by the character of Hanna herself, and her forest upbringing. Even though the music is sometimes processed, it is always based on something real and organic rather than pure electronics. We often used layers of woodwind instruments (including some fairly unusual ethnic flutes and pipes) as a way of linking Hanna to the natural world in which she was brought up, and also to try and capture her fierce animal spirit and her sense of wonder as she experiences the `new world' beyond the forest." - Ben Salisbury
