This one’s easy to describe: Very ordinary.
Nothing really sticks out with Georg’s Planets. There’s nothing here that would prompt critics to say things like “Sir Georg does [insert Planets moment here] so well”, or “Sir Georg’s [insert another Planets moment here] is far ahead of the competition” etc. There’s none of that here.
Solti’s Planets is perfectly acceptable. (How’s that for damning with faint praise?)
Trivia: At 4:41 in “Mars” a trumpeter fluffs a note, and it sounds like a “meow”. From now on I want to call this The Cat Planets.
More Trivia: Also in “Mars”, this time at 5:43, a horn makes a mess of a note, and it sounds like something’s being strangled. I hope that cat’s OK.
