DESCRIPTION:
The first Hauschka's album, Substantial, was released in 2004 on the Cologne label Karaoke Kalk, followed in 2005 by The Prepared Piano on the same label. On this second album Bertelmann explored the possibilities of the prepared piano by wedging pieces of leather, felt or rubber between the piano strings, wrapping aluminium foil around the hammers, placing small objects on the strings or joining them together with guitar strings or adhesive tape. In 2007 the remix album Versions Of The Prepared Piano was released, featuring new interpretations of the original tracks by the likes of Eglantine Gouzy, Barbara Morgenstern, Nobukazu Takemura, Wechsel Garland, Frank Bretschneider, Mira Calix and Tarwater.
In 2007 Bertelmann signed a recording contract with 130701, an imprint of FatCat Records. On the 2008 album Ferndorf he collaborated with cellists, trombonists and violinists. Following a concert performance with the Magik*Magik Orchestra, Bertelmann decided to integrate other musical instruments into his compositions, and in January 2010 the resulting works were performed in San Francisco by an orchestra led by Minna Choi. With Ian Pellicci as the sound engineer, they were recorded in John Vanderslice's Tiny Telephone studio. Volker Bertelmann then recorded the piano tracks at Studio Zwei in Düsseldorf, and the album Foreign Landscapes was released on the 130701 label later that year.

Hildur Ingveldardóttir Guðnadóttir (born September 4, 1982) is a classically trained Icelandic cellist who has played and recorded with the bands Pan Sonic, Throbbing Gristle and Múm, as well as her solo project Lost in Hildurness. She has also toured with Animal Collective.
In 2007 she released a solo album, Mount A, on which she attempted to "involve other people as little as I could." It was recorded in New York and Hólar in the north of Iceland. 2009 saw the release of her second solo album, Without Sinking on the UK-based audio-visual label, Touch.
As well as the cello, Hildur also sings and arranges choral music, once arranging a choir for performances by Throbbing Gristle in Austria and London. As a composer she has written a score for the play Sumardagur ("Summer Day") performed at Iceland's National Theatre.
