They are joined by Adwaith, Aleighcia Scott, Alffa, Campfire Social, Eadyth, Marged, Nia Wyn, No Good Boyo and The Pitchforks, who were each selected by a panel including tastemakers from Moshi Moshi, Drowned In Sound and PRS Foundation.
All Horizons 2018 artists will take part in various showcases throughout the year to support and highlight emerging Welsh talent and introduce them to wider audiences.
Activities will kick off at the BBC’s Biggest Weekend Fringe Festival in Swansea this week, where DJ Huw Stephens will showcase some of the acts live on BBC Radio Cymru.
In the three years of the project, previous Horizons alumni include Candelas, CaStLeS, Violet Skies, Kizzy Crawford and Seazoo.
New this year, Horizons has hand-picked 12 Horizons bloggers who will help spread the word about the 12 new acts throughout 2018.
Lisa Matthews, from Arts Council of Wales, said: ‘We’re proud to support Horizons for a further year and see another 12 artists have a creative and potentially career changing year. There have been some incredible opportunities created so far and we’re looking forward with excitement more incredible music experiences.’
Bethan Elfyn, project manager of Horizons at BBC Wales, added: ‘The Welsh music scene has probably never seen such a time as this - a real explosion of creativity in so many towns and cities, and so we’ve been absolutely spoilt this year with the selection of talent.
‘We’ve got an incredibly diverse shortlist of artists, and we can’t wait to follow their journey for the next year. A few of the acts will be familiar names but there’s also bound to be one or two musical surprises for people to discover.’
