Cardiff singer Gwenno recently won the Welsh Music Prize 2015.
But those unaware of the artist before will now see her adorning the outside wall of Cardiff's famous venue Clwb Ifor Bach on Womanby Street.
The 34-year-old said she was " incredibly honoured" to see herself in the 12 x 38 metre mural.
"I remember Clwb when I was growing up, I probably went to see my first gig there, dragged along to a Welsh Language Society event with my mum," said Gwenno, whose full name is Gwenno Saunders.
"Clwb is a huge part of everyone's heritage from Wales, most bands have played here.
"I'm incredibly honoured that they thought my face was worth putting up there," added the singer, who recently became a mother to son, Nico.
Gwenno was first approached by designer Mark James about the mural, which he designed for the Get it right campaign.
The campaign aims to prevent piracy in music and television, by promoting the value of creativity in the UK and raising awareness of genuine online content services.
"Gwenno's album had just come out and was getting a lot of attention," Mr James said.
The sci-fi themed album Y Dydd Olaf, sung in both Welsh and Cornish, was inspired by Owain Owain's 1976 Welsh novel of the same name.
"The original idea was to be quite political and to make a statement," he said.
Mr James's design, one of Cardiff's largest street art projects, was sprayed painted onto the building by local street artists Rmer, Zadok and Karm, in under three days.
It will remain on the walls of Clwb Ifor Bach for the next six months.

Bahman Daroshafaei, who has dual British and Iranian citizenship, was arrested at his home in Tehran on 3 February on unspecified charges.
One friend told the Reuters news agency that his release on Tuesday "was a surprise to him".
Mr Daroshafaei has been working as a translator since leaving BBC Persian around two years ago.
His family said that his passport had been seized after he returned to Iran.
Since then, he had been questioned dozens of times by the intelligence ministry about his activities as a journalist, the news website Iranwire reported.
A Twitter campaign run by his friends and colleagues, @FreeBahman, posted a photograph of Mr Daroshafaei standing outside Tehran's Evin prison on Tuesday.
"Good news: Bahman has been released on bail," said the caption.
In November, two prominent journalists were arrested as part of what appeared to be a crackdown on writers, artists and other cultural figures in Iran. Isa Saharkhiz and Ehsun Mazandarani have been accused of acting against national security.
The previous month, poets Fatemeh Ekhtesari and Mehdi Mousavi and filmmaker Keywan Karimi were handed lengthy prison terms by a court after being convicted of charges including "insulting sanctities and propaganda against the state".
