A reference archive of the recorded output of 24 orchestras of the tango Golden Age. Every entry carries the vocalist (or Instrumental), the ensemble formation, the exact recording date, the label and the disc/matrix numbers — the details that identify one specific take rather than one song. 9255 of 12529 recordings (74%) link straight to a verified recording of that exact take; the rest open a search pre-filled with the title, vocalist and year. Each orchestra also carries its personnel history, set out year by year and instrument by instrument.
Method and checks
Every field was compiled programmatically from published discographies — nothing typed or guessed by hand. The checks applied:
- Vocalist tenures. Each singer's observed year span is exposed through the filters, so a name falling outside its documented period is immediately visible.
- Label eras. Label and date travel together on every row, so each recording can be checked against the orchestra's known contract history.
- Verified links (9255 of 12529, 74%). A direct link was kept only where the target's own title independently confirms that take — naming the vocalist and the recording year, or, for instrumentals, carrying the right year while naming no singer, since a singer's name there would indicate a different version. Candidates naming a rival bandleader were discarded. Rows that could not be confirmed deliberately fall back to a search rather than a guessed link.
- Independent cross-checks. 64 recordings were matched against a specialist reissue catalogue's own recording dates: 64 of 64 agreed exactly, to the day.
- Personnel data. Parsed into structured fields — year, instrument, musician — rather than carried over as prose, then de-duplicated per section.
Coverage: depth varies by orchestra. Francisco Canaro, Roberto Firpo, Juan D'Arienzo, Osvaldo Fresedo, Francisco Lomuto, Aníbal Troilo are documented in detail; the thinnest listings — — cover only a fraction of what those orchestras actually recorded. Per-orchestra counts are shown beside each name in the selector above, and verified-link coverage is on each orchestra's tiles.
Note: many titles were recorded several times, with different singers and in different years — read the vocalist and date columns before following a link.
