Kate has been particularly enjoying performing recitals of music from the pleasure gardens, the anniversaries of Thomas Arne and William Boyce sparking an initial interest and giving opportunities to explore the wealth of this music even further. Her solo CD Delicatessen with harpsichordist Steven Devine and recorded at the Sendesaal in Bremen gave opportunity to record some of this repertoire. This has now been followed up by Delicatessen II, which took his repertoire into even more unknown territory. These two CDs have led to recitals across the country and also to Europe where they have become well knon for this repertoire. Kate and Steven also developed programmes of music based around the domestic music of the Bach Household. This led to performances at St John's Smith Square and Radio 3 as well as many Festivals across the country, and ultimately a recording of The Notebooks of Anna Magdalena Bach.
