folk rock group Têtes Raides, the string quartet Quatuor à cordes, guitarist and composer Olivier Mellano, and author Mathieu Boogaerts. The soundtrack for Amélie saw for the first time the introduction of a full orchestra, the 35-member Ensemble Orchestral Synaxis, and of an ondes Martenot played by Christine Ott. Both will participate in the recording sessions for his next album, L'Absente, which also includes American singer-songwriter and multi-instrumentalist Lisa Germano, Belgian actress and singer Natacha Régnier, Neil Hannon, and Têtes Raides, among others. Tiersen's list of collaborators continues to grow. His second live album, C'était ici, recorded during three concerts performed in February 2002 at the Cité de la Musique in Paris, features more than 50 musicians. Yann Tiersen & Shannon Wright, a collaboration album with American singer and songwriter Shannon Wright, was released in October 2004, and his 2005 album, Les Retrouvailles, features vocals from Stuart Staples of Tindersticks, English actress and singer Jane Birkin, Breton singer and songwriter Miossec, Elizabeth Fraser, the vocalist for the pioneer alternative rock group Cocteau Twins, and the Orchestre National de Paris. The subsequent world tour produced his third live album On Tour, which replaced the multi-instrumental ensemble of Les Retrouvailles with a more rock-oriented sound. The soundtrack to Tabarly saw Tiersen return to minimalism, in fact most of the compositions featured on the album are for solo piano. But his two subsequent albums return to have a rock-oriented sound, with the only difference that Skyline has a higher number of contributors than Dust Lane. Tiersen has contributed, either in part or in full, to the realization of several records among which stand out "Gin Soaked Boy" and Absent Friends by The Divine Comedy, Vingt à Trente Mille Jours by Françoiz Breut, Lucky Dog Recordings 03-04 by Stuart A. Staples, and Li(f)e by Sage Francis, as well as records by Noir Désir, Têtes Raides, The Married Monk, French electronic trio Smooth, Katel, David Delabrosse, Christine Ott, or Miossec. In 2011, Tiersen, with Lionel Laquerriere and Thomas Poli, has also started Elektronische Staubband, a side project on electronic music. This new project is expected to lead to the release of a new album in 2013. Charity work In 2011, Tiersen collaborated with the Yellow Bird Project (YBP) to design a t-shirt, which was sold to raise money for Médecins Sans Frontières (MSF). The main reason he chose to support MSF, is for their work
