Anhrefn (Welsh for "Disorder") were an influential punk rock band from Bangor, North Wales and formed in 1982, and initially sang only in Welsh. The band were not supported by Radio Cymru or Welsh-language TV channel S4C, beyond an occasional interview, and bassist Rhys Mwyn became known as an outspoken critic of the Welsh pop industry.
Mwyn (born Gareth Rhys Thomas) set up his own Recordiau Anhrefn label in 1983, helping to promote like-minded Welsh bands as well as their own music. The band were championed by John Peel and recorded three sessions for his BBC Radio 1 show; Peel even travelled to Wales to see the band perform. The band played up to 300 gigs a year at their peak, touring Europe several times, including Czechoslovakia, Germany and the Basque Region of Spain.
Original members Hefin Huws and Dewi Gwyn left the band in the late 1980s and were replaced by Dylan Hughes (formerly of Y Cyrff) and Sion Jones (formerly of Maffia Mr Huws).
The band made their first English language recording in 1994, on a single with actress Margi Clarke (they released a cover of Cole Porter's "Anything Goes" as a single), and had earlier collaborated with Pauline Murray (of the punk band Penetration) in 1990, who co-wrote Llygaid wrth Lygaid, which is on the B-side of the cassette version of Rhedeg i Paris.
In 1995 the band changed musical direction to a more techno sound and released Hen Wlad fy Mamau – Land of My Mothers, It also featured producer Ronnie Stone who aided the duo in creating a world beat collection of re-mixed Welsh folk music, samples and electronic sounds featuring Welsh singers Siân James, Lowri Ann Richards, June Campbell Davies and Elinor Bennett, Punjabi rapper Harvinder Sangha and African dub collective Zion Train.
The band soon split after that release, but brothers Rhys Mwyn and Sion Sebon formed a new band, Mangre, in 2000. Mwyn went on to manage the Crai label and work as an agent. He managed Catatonia and more recently Jeb Loy Nichols, which prompted a resurrection of Recordiau Anhrefn.
In 2007 Anhrefn reformed briefly without Mwyn, with Ryan Kift on vocals.
Super Furry Animals drummer Dafydd Ieuan was also in Yr Anhrefn for a time, playing on their 1993 Peel session, and SFA had started out as a techno band, supporting Yr Anhrefn on a tour of France in 1993.
In 2016, Rhys Mwyn and Sion Jones teamed up with Neil Crud and Alan Matthews (both previous members of North Wales punk bands 4Q and Sons Of Selina) to play Anhrefn's debut album 'Defaid, Skateboards a Wellies' live under the banner Welsh Rebel Outpost
Also in 2016 Rhys Mwyn became the new bassist for Welsh punk band White Ether.
