About Deep Groove Mono

Deep Groove Mono is a record collecting blog designed, developed, written, and maintained independently by Richard Capeless. Deep Groove Mono aims to provide collectors with unprecedented resources related to their hobby, and to document the author’s collecting experience. Deep Groove Mono focuses on classic jazz originally released on mono vinyl LPs and 78 R.P.M. shellac disks. The name of the blog is a synthesis of two telltale characteristics of many vintage records covered here. A “deep groove” is a circular indentation in the label area of many of these records, while “mono” describes the single-channel audio format that was standard during this time.
