Loretta Problem is bunch of Finnish punkhippies mixing celtic tunes with punk-rock since 1991.

”Scandinavia has some really interesting and very good, Celtic-Punk bands and Finland’s
The Loretta Problem are one of the best!”” Some might say that the problem with The Loretta Problem is that they don’t release enough music. Others would say they might not release lots of music but when they do it is always up there with the best in Celtic and/ or Folk-Punk.”
