There are, at least, two artists known as Fink: 1) A Brighton-based acoustic folk / blues / electronic artist. 2) A Hamburg, Germany alt-country band, founded mid-90s & disbanded in 2007.
These are photos from concerts where Fink played, so they may be of other bands that played the concert as well.
