Leaving Home - Simon Rattle on 20th Century Orchestral Music

I bought this set of DVD at Mongkok this evening - it only costs HKD285! 7 DVDs!! It is published by a Chinese press (with a different cover). It is not even available on Amazon yet.

Simon Rattle leads the City of Birmingham Symphony Orchestra, discussing and playing classical music of the Twentieth Century - Wagner, Strauss, Mahler, Sch?nberg, Berg, Webern, etc. This is a relatively new area for me in Classical Music. This is surely a bargain!
