The few tango recordings I have in my collection are pretty much from the 1930's, so I can't help on this one.
edit: This CD seems to have Roberto Firpo recordings beginning in 1920. Don't know if that helps.
Put Wilbur Ware on the front end of that and it makes even more.
I've always heard much more of a Ware influence in Malachi Favors' music than I have Garrison. Not to minimize the possibility of Garrison's influence in any way.
Has there ever been a talented/unbelievably sloppy team like the current Cowboys? Time to cut ties with Romo and Bryant and probably Garrett and change that team. I'm not even a Cowboys fan, but they're just horrible to watch.
