Björk's sixth full-length studio album, "Volta", was released on 7 May 2007. It features 10 tracks. It features input from hip hop producer Timbaland, singer Anohni, poet Sjón, electronic beat programmer Mark Bell, kora master Toumani Diabaté, Congolese thumb piano band Konono No 1, pipa player Min Xiaofen, and, on several songs, an all-female ensemble from Iceland performing brass compositions. It also uses the Reactable, a novel "tangible-interface" synthesizer from the Universitat Pompeu Fabra in Barcelona, which on "Volta" is played by Damian Taylor. The first single from the album, "Earth Intruders", was released digitally on 9 April 2007 and became her second-ever "Billboard" Hot 100 entry in the United States. "Volta" debuted at number nine on the "Billboard" 200 albums chart, becoming her first top 10 album in the US, netting week-one sales of 43,000. The album also reached number three on the French albums chart with sales of 20,600 albums sold in its first week, and number seven in the UK Albums Chart with 20,456 units sold. The second single from the album, "Innocence", was digitally released on 23 July 2007, with an accompanying music video chosen from a contest conducted through her official website. "Declare Independence" was released on 1 January 2008 in a super deluxe package including two 12" vinyls, a CD, and a DVD featuring Gondry's "Declare Independence" video. "Wanderlust" was subsequently released in a similar format, featuring Encyclopedia Pictura's short film directed for the track, shot in stereoscopic 3D. The fifth single released from the album was "The Dull Flame of Desire", featuring vocals by Anohni.
