Truth be told, I'm not much of a mass collector as anyone expects to be but I recently got Agnetha Fältskog's 'Elva kvinnor i ett hus' on vinyl, Cupol 1st pressing... fantastic sound as is. I wonder if Agnetha herself was the master engineer of that album?
That's the one album I'm definitely planning to buy on vinyl one day too. Absolute masterpiece! I believe it will be re-released probably next year together with När En Vacker Tanke Blir En Sång (great album as well), following the re-release of her first three Cupol LPs. I guess Michael Tretow was the engineer though... Agnetha "only" produced the record.
