Quinteto Astor Piazzolla (read annotation before use)

the status of this group as a unique entity is uncertain;
discogs does not differentiate this from Astor Piazzolla y su quinteto during the 1960s till early 70s era, but rather just accounts for group member changes during its existence
in any case, for later recordings from 1978 on, the use of this name would very likely refer instead to Astor Piazzolla y su Quinteto Tango Nuevo so consider using that.
