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 American music originally released on 78 R.P.M. shellac disks and mono vinyl LPs and 45s. 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.

About the Author

Richard Capeless is a college math instructor located in Queens, New York. Born in 1980, he grew up listening to hip hop and developed his knowledge of the genre during high school. Hip hop then served as a gateway to all the great classic genres he now collects: jazz, rhythm & blues, doo-wop, rock & roll, and the blues. Richard’s approach to the hobby is that of a sound engineer and DJ. He is passionate about the history of music and audio, and in 2019 he presented to the Audio Engineering Society on the life and legacy of recording engineer Rudy Van Gelder. (Photo credit: A.
