Riho Sibul is the leader of Ultima Thule, an Estonian rock band. Formed in 1986, they have been one of the country's most influential bands of the 1980s and 1990s. Their style combines blues-rock with either witty or poetic lyrics, often incorporating elements of Estonian folk lore and traditional music. In addition to his work in Thule, Sibul is also a renown solo artist with three highly acclaimed albums. He is, as claimed by many, the most unique guitarist in Estonia with influences from Jimi Hendrix, Jeff Beck, Wayne Krantz, Brandon Ross, Kevin Breit and Bill Frisell to name a few.
