THE NORTHWEST MUSIC ARCHIVES documents audio recordings produced in the Pacific Northwest area of North America. We present data as labelographies (by using our “Search by Label” function) that note what recordings were issued when by which labels — and also (by using our “Search by Artist” function) as discographies that reveal what recordings were created when by which local musicians.
AUDIO HISTORY: To gain a greater sense of the deep back-story of our main topic, please click on our NW History page. It includes links to essays covering topics including the first record ever cut in Seattle and an overview of recording history in the Northwest.
CONTACT: We welcome the contribution of relevant discographical data from fellow music fans, musicians, and labels. Please submit info (or recordings) via our Archives Facebook page.
SOUND CARRIER FORMATS: This site notes the different “sound carrier formats” (and their varying configurations) that recordings were released in. They include discs (16 rpm, 33 1/3 rpm, 45 rpm,& 78 rpm), player-piano rolls, reel-to-reel tapes, cassettes, 8-track cartridges, compact discs (CD), and even digital downloads.
SERIAL NUMBER: A record’s Serial Number (or “Catalog Number”) is typically found in relatively large type-font on the paper label at the center of a disc, and will typically be the same number on both sides of that disc. It is intended as the record company’s means of organizing the sequence in which their various recordings are produced and/or released. Cassettes and CDs likewise have Serial Numbers noted on them.
MATRIX NUMBER: A Matrix Number is an alphanumeric code that is often printed on a record’s paper label (but it is typically in a smaller type-font than the Serial Number). A Matrix Number is intended for the internal use of the manufacturing plant — mainly to assign a filing/storage number for the metal disc-stamper — but they can also provide useful information to discographers about the edition of the record, and/or when it was pressed.
STAMPER CODE: A Stamper Code is an alphanumeric code stamped (or hand-etched) into the run-out area of a disc (the non-grooved area between the final band on a disc’s side and the paper label). There are typically two parts to Stamper Codes: the Serial Number (or Matrix Number), and extra information which can include a “take” number (reflecting which rendition of a song, among several the artist may have recorded during a session, was selected for release). It may also include disc pressing-plant codes or logos, the initials or signature of the disc-cutting engineer, and cutting or copyright dates. California’s Monarch plant employed what is called a “Delta Code” — a number preceded by a pyramid-shaped symbol (which this site denotes with a ^ digit) that can be helpful in dating when that disc was pressed.
DATES: Listed dates on this site are generally record release dates, rather than recording session dates (as the latter are not generally documented for most recordings in recent decades). All noted dates are presented in the Year-Month-Day format of YY-MM-DD. [Example: for a recording released on January 21, 2014, our site would show 2014-01-21]
SONG PUBLISHERS: Publishing companies are noted if they are listed on a recording’s label — as are various performing rights organizations that they were associated with, including ASCAP (the American Society of Composers, Authors and Publishers) and BMI (Broadcast Music, Inc.).
PETE BLECHA launched the original Northwest Music Archives in 1982 as an independent historical preservation project which produced free public exhibits around Seattle relating the history of the region’s recording industry. In 1983 he began years of penning the path-breaking “Northwest Archives” history column in The Rocket magazine. He also served for a few years on the Northwest Area Music Association’s Hall of Fame Committee. Then, after spinning rare local discs as a radio DJ at KCMU, he served for 8.5 years as Senior Curator at Seattle’s music museum, the Experience Music Project (today’s Museum of Pop Culture, MoPop). A long-time member of the Pacific Northwest Historians Guild, and the Association for Recorded Sound Collections (and has served several terms on their Excellence in Publications Committee), he is the multiple award-winning author of twelve books, and has served as a Staff Historian & Contributing Editor for Washington State’s online history encyclopedia, HistoryLink.org since 2001.
