Frank Kaumanns has 3 subway to sally concerts.

Subway to Sally was founded in Potsdam, Germany, in the early 1990s. It is a rock band with clear folk and medieval influences, later also with gothic and metal elements added to the mix. With their continuous inclusion of oriental sounds and elements of classical music (noted for instance by the use of the arrangements of the backup vocals) and the use of instruments less frequently seen in metal bands, such as bagpipes, shawm, violin, hurdy-gurdy and lute, the band has acquired the label of medieval metal.
