Frank Kaumanns has 8 In Extremo concerts.

In Extremo (Latin: At the Edge) is a German medieval metal band originating from Berlin. The band's musical style combines metal with medieval traditional songs, blending the sound of the standard rock/metal instruments with historical instruments (such as bagpipes, harp, hurdy-gurdy and shawm). Versions of well-known traditional/medieval ballads make up the main part of their repertoire, but the band has written an increasing share of original material in recent years.
