The 2001 Warner album is a regular U.S. release. The international release, and
the one in Europe more specifically, was produced under the foreign name of the film, Harry
Potter and the Philosopher's Stone. That foreign version is a 2-CD product, though only one
of the CDs has John Williams music, and that material is identical to what you hear on the
American release. The second CD only contains multimedia.
The expanded bootlegs started circulating around the secondary market in 2002 and often
contained different contents, but all existed on two CDs. The 2018 La-La Land set contains all
three of Williams' scores for the franchise. It is limited to 5,000 copies and available
initially for $100 through soundtrack specialty outlets.
