Spelk is a Yorkshire-based new music collective whose core members, all established artists in their own right (Iain Harrison, saxes; Murphy McCaleb, bass trombone; Kate Ledger, piano/keyboards; Tim Brooks, piano, keyboards; Nick Williams, artistic associate) can be expanded as and when required. They have all worked in a wide variety of genres including contemporary, experimental and pop music. and this is reflected in their aesthetic approach and the range of their continually expanding repertoire.
