the status of this group as a unique entity is uncertain; discogs does '''''not''''' differentiate this from [artist:21c07728-e057-4718-b2bb-1b4c632208f3|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 [artist:d2f6d6d9-f45d-47bb-a48e-1943ee93f456|Astor Piazzolla y su Quinteto Tango Nuevo] so consider using that.
