Rekorder 8 is the best release in the catalog of 11 records. The original 10 volumes have been met by a release now known as Rekorder '0'. That being said, if you enjoy Rekorder 8, then you should find releases with numbers 7, 9, 10 and '0'. I do believe these have been my favorites for quite sometime and if you ever collected Mike Ink's "Studio 1" or Hawtin's "Concept" series, Rekorder is kind of a collectable series. The early numbers still are not as good as the later releases but because of the fact that the later ones are so good, I want the whole collection. I think that would be a great add to any collection.
