THEY specialise in medieval music and since the early Nineties have played at festivals and historic venues throughout Europe.
Misericordia are a four-piece ensemble who use medieval instruments such as hurdy gurdy, bagpipes, gothic harp, citole, recorders and voices.
They play the music of plague and pilgrimage, which is actually much more entertaining than it might sound. There was, after all, plenty of drama in the 14th century, which was plagued by the Black Death, warfare and social upheaval.
It was a period which produced some true oddities; processions of German flagellants, a French king who thought he was made of glass, a hysterical dancing mania and a war between two popes.
But people sang and danced to some of the most poignant, intense and rhythmically exciting music of all time.
Tomorrow you can hear that period brought to life by Misericordia at the Square Chapel arts centre in Halifax.
Tickets are £9 (concessions £7) and are available from http://www.square chapel.co.uk or by phoning 01484 349422.
