In the 1990s in the Gwynedd village of Waunfawr, a teenage band called Beganifs were formed.
A few years later, they'd changed their name to Big Leaves and had some success - famously Radio 1 DJ Mark Radcliffe played their single, Racing Birds, twice in a row.
- Mei: vocals, guitar
- Osh: keyboards
- Fflos: guitar
- Daf: drums
Big Leaves eventually split in the early 2000s, but brothers Osian and Meilir Gwynedd couldn't keep away from the music scene, hence Sibrydion.
Starting high, their first gig was at the National Eisteddfod in 2004. "It was Mei playing on his own with a drum machine for company," they recall.
Within the first year or so of Sibrydion's life, they'd recorded a session for Radio Wales' C2, and won the station's Best Session award and had their song Dafad Du chosen as the theme to S4C's music programme, Bandit.
Their debut album, JigCal, was very well received inside and outside the Welsh-language music scene. Its exuberant, melodic indie rock style is pleasingly quirky, in keeping with the origin of its title.
"We named it after a 'careers computer' that declared Osian should be a bus driver and that Mei should be a monkey attendant in a zoo," they say.
In 2007, Sibrydion released their follow-up album, Simsalabim.
