working with a variety of musicians, inviting Paddy Moloney (of The Chieftains), Jim Kerr (of Simple Minds), Khaled and Youssou N'Dour to be in his very international 1 Douar / 1 Earth album. The 1998 French-language hit "La Tribu de Dana" by rap trio Manau, one of the best-selling French singles of all time, featured a very similar musical arrangement to Stivell's "Tri Martolod". Although Stivell sued Manau for the unauthorised sampling, the group claimed that they had modified the original sufficiently, through the addition of lyrics and other changes, to avoid any charges of plagiarism. Stivell is now credited for a part of "La Tribu de Dana"'s arrangements. Stivell's CD album Again in 1993 was the base for a new wave of his popularity, especially in France and Brittany. Other albums received good critical reviews, such as Brian Boru or 1 Douar ("1 Earth"). In 2002 Stivell released Au-delà des mots ("Beyond Words"), his twenty-first LP. The album featured him playing six different harps, specially dedicated to the Celtic Harp Revival's 50th anniversary. In 2004, to celebrate the 50th anniversary of the Celtic harp revival in Brittany, he wrote a book in collaboration with Jean-Noël Verdier: Telenn, la harpe bretonne ("Telenn, the Breton harp"). The same year, the DVD Parcours was published by Fox-Pathé. In 2006, a new CD album called Explore came out in France and other countries, distributed through Harmonia Mundi. The album explored fusions of Celtic music with electro-rock, raga and hip-hop with a unique and personal vocal style and an original mix of lyrics in Breton, English and French. In 2009, the title of his album Emerald celebrated his emerald anniversary with his fans (i.e. forty years together) and paid homage to the sea and the Celtic lands (color blue-green, Glaz in Breton language). In 2013, a new CD album and DVD called Olympia 40th Anniversary came out in France (Universal) as a result of the concert performed at the Olympia mythical music hall on 16 February 2012. On 2 October 2015 Stivell released a new CD album called AMzer: Seasons through WorldVillage in France (and other countries), his first one of the 2010s, coinciding with his career's 50th anniversary. The album is also available as a "Leclerc limited edition" including 3 bonus tracks (2 alternative mixes and a brand new instrumental) and a 60-page booklet.
