Sibrydion (Welsh pronunciation: [sɪbˈrədjɔn]) are a band based in Cardiff, originally from Waunfawr in north Wales, formed by brothers Osian (keyboards) and Meilir Gwynedd (vocals, guitar), formerly in the band Big Leaves.
[2] They went on to record a session for C2 and their song "Dafad Du" was used as the theme to the S4C music programme Bandit.
By 2007, the band became larger to vary their live sound, and these are the members at present: Meilir Gwynedd (vocals, guitar), Osian Gwynedd (keyboards), Dan Lawrence (guitar), Rhys Roberts (bass) (also a member of Anweledig), and Dafydd Nant (drums, also a member of BOB.)
Their second album, Simsalabim was launched at the National Eisteddfod in 2007, on the Copa label.
[1][3][4] The album received a four-star review from the Sunday Times,[3] and was described as "a playful, melodic masterpiece" by the Daily Express, who also gave it 4/5.
