Cate Le Bon - she supported Gruff Rhys (of the Super Furry Animals) on his 2007 solo UK tour.
Free music gigs are on offer at the Glynn Vivian Art Gallery in Swansea.
This art and music fusion will next come together at 3.30pm on Friday 11 December with Welsh indie-electronica-folk singer, Cate Le Bon.
Her latest appearance is in the wake of a very successful year for the songwriter, including being featured in MOJO magazine's top 50 albums.
She has appeared on Gruff Rhys's Neon Neon album, and has just released her debut album, Me Oh My.
Mixing mournful vocals with folky electronic sounds, Le Bon has played Glastonbury, Latitude and the Green Man Festival.
Gordon Dalton, the museum's learning and interpretation officer, said: "I just wanted to get more, and different kinds, of people in the gallery.
"The Free: 30 Sessions just seem to have worked. Next year we will be having a broader spectrum of films and gigs, and we'll be staging those at different places even when we're closed for refurbishment."
The gallery, which is almost a hundred-years-old, is scheduled for a £6m renovation, and is part of a wider plan to create an "arts quarter" in the city.
Future gigs will include Euros Childs, Spencer MacGarry Season and Barefoot Dance of The Sea.
And in the run up to Christmas the Glynn Vivian will also host community groups and choirs as they serenade audiences with festive verses around the twinkling 20-foot-high Christmas tree.
