ASIN B01KAU19YU seems the common ASIN for the Amazon digital releases of this album.
I am a bit confused.
When I open this ASIN on Amazon, I see not a digital, but a physical release (“Format: Audio CD” directly under the CD name). Strangely enough, for this ASIN Amazon does not show any meta-info, such as label, release date etc.
When I open B00000E4L7, I see a physical release as well, but this time with a label (L’oiseau-Lyre) and release date (November 8, 1991)
I could access a digital release with B0051U6JWC. For this ASIN Amazon shows a label (Decca) and a release date (May 31, 2011).
Based on Amazon meta-info, it looks like the right ASIN for a physical release is B00000E4L7, and for a digital release B0051U6JWC.
