For the seventh time, Tom 'The Perc' Redecker opens his sound archive, in which many delicacies are slumbering from around 40 years of German underground music. This collection is dedicated exclusively to the analogue keyboard Casiotone MT 400V, affectionately called Carola, which Tom bought in 1986 in Bremen. The sound of Carola is unique and not to be confused with other comparable keyboard instruments.
