“I try and find a language which doesn’t disregard everything which has happened in the twentieth century” says Burrell; “that does acknowledge Stravinsky and Schoenberg, Boulez and all these others, whilst being simple enough to work for the concert hall, or church, or for young people – the wider community in some way. But which acknowledges that this is where we are – we can’t go back. You can’t unpick the twentieth century.” From Composition Today.
Part of the British Music Collection also contains composer files, articles, essays, newspaper cuttings etc. There wasn't much time to peruse these, however, this is an example of the type of material available for research. In addition to this, there is a link to Diana Burrell talking about creating composition inspired by architecture below at London City Hall in 2009.
