Composer Neil Rolnick will perform an evening of compositions for solo laptop computer. The concert will include Rolnick’s pieces from the early days of sampling technology, in the late 1980s, when he first explored what are now called “mashups” of existing music to create new works. It will also include some of his most recent works, which reconsider this approach to composing in the light of 30 years of technological development and the revolution in thinking about sampling.
