Every year the Churches as Podium Workgroup organises two sets of concerts in the series of Saturday Afternoon Concerts.
Various churches in Zwolle, large and small, are used to stage these events, in which choirs, ensembles and soloists perform music from a variety of genres and periods.

The carillon of the 'Pepperpot' (Peperbus, The tower of the Church of Our Lady) plays from 13:30 before each concert.

The concerts last about 45 minutes. The audience is invited to contribute at least € 3 per person.
