The fastest way to have this chievy is obtain the first 3 LPs (actually, only the third one is "missable"):
TROIS MARCHES MILITAIRES (single):
Chapter 1 -verse 4, Vigrid central station (Gaudì style). Impossible to miss, ‘cause you’ll obtain it after beating the first “Beloved” boss.
QUASI UNA FANTASIA (single):
Chapter 2 -verse 7, another LP you cannot miss, ‘cause is the prize for the battle with those 2 “Beloved”.
FANTAISIE IMPROMPTU (2 pieces):
Chapter 3 -verse 4, price for the first “Fairness” fight.
Chapter 3 -in Paradiso, garden of light (around verse 10), on a little island behind the heaven gate you came through. Walk on water, you cannot sink.
If you are too far in the game, you missed the third LP and you don't want to start all over to have a third disk&chevy, then read my "record fanatic" achievement solution to have to exact position of each of them.
