Tango.info performance date source
Overview
This page gives some details about tango.info performance date sources.
Sources that contradict each other
For each performance date having a single source, or having only agreeing sources, the date given in this source, or these sources, has been used. For contradicting sources one given date has been picked.
Trustworthiness
Since there are sources that contradict each other, at least some are wrong.
The most trustworthy are probably the dates given in the graphics linked from The Argentine Talking Machine Works - Buenos Aires, since they might be the closest to the event of performing.
The trustworthiness of other sources is hard to estimate, since most don't give their sources, or give a source that doesn't give its source, e.g. one discography referencing another discography.
Examples
- Photographs or scans of paper where recording/performance dates had been written down by the record company, e.g. The Argentine Talking Machine Works - Buenos Aires
- 78 rpm labels contain the year, e.g. T.K. from 1955: https://tango.info/?q=s-54
- Performers emailed dates of their own performances, e.g. Quinteto Angel, Ensemble Hyperion
- CD covers
- Discographies (e.g. todotango.com discographies, Juan D Arienzo discography by Johan, Francisco Canaro discography by Christoph Lanner, Encyclopedic Discography of Victor Recordings)
- LP covers having a recording date

Chris, UK, 2011-04-06 I wonder if many tango.info dates are actually release dates rather than recording dates, and hence the summer dip actually corresponds to seasonal variation in consumer demand.
