This is another really great volume of orchestral studies from Richard Muller-Dombois. The presentation may be a little old-fashioned but the content is bang up-to-date. Each of these challenging extracts has been expertly arranged with no alterations to the orginal and the instrumentation of the accompaniments fully annotated. This is such a great way to learn these important solos, even if you're not playing the solo line. Expensive it may be but this book is very much worth the money.
