Haven't seen Strange's book, looks interesting, but a couple things have changed since 1970. One I have seen and strongly recommend is "Computer Music: synthesis, composition, and performance" by Dodge and Jerse (1997 2nd Ed.). It's a great technical -but readable- reference to learn important bottom-up concepts in detail (including graphs and equations). No computer needed! (Of course, some things have changed since 1997 too. But basics are basics.)
