Earp is way too long in that form, but Goldsmith's First Knight is great no matter how long it is! First Knight!
First Knight plays way better in the longer form. I always considered it a 3.5 star score on the single disk release, but the LLL edition is a 5 star score.
If I didn't own any of those scores on CD and had to choose just one, it would be Young Sherlock Holmes, without a doubt. It's one of my all-time favorite scores, and therefore one of the greatest scores of all time.
Take the $30.00 and take your girlfriend or wife to GOLDEN CORRAL and eat to your heart's delight.
Yep. And if you can't decide between your wife and girlfriend, take them both.
However, if you must spend it on music, my advice would be to buy a budget cycle of symphonies by one of Sibelius, Nielsen, Prokofiev, Shostakovich or Vaughan Williams. I think you'd learn more about film music from one of these than you would from ALL your original choices put together.
