i had just read the Bjork Homogenic edition of this series and it focused a lot more on the production and just Bjork's overall life at the time and all that lead up to the album and the technology behind it.
the Erotica edition seemed more about the culture at the time and not much about the actual making of the album. its an interesting read but didnt do much to add to the history of the album, especially for those looking to read about the production.
