Yes, she was IQ's GF, but I believe she worked a lot in local clubs before and after that. For whatever reason. And she did make one other record, for Time, before the BN date. In 1959, actually. And she stayed active for a good long while too.
Mention was made earlier of Gloria Lynne...Gloria Lynne sold a LOT of records to African-American audiences. Successful or not (musically and career-wise) Dodo Green was part of that market/society.
I don't find her that bad, actually. But a little does go a long way. Still, I hear people just reflexively ridiculing her with no real awareness of how/why/where that kind of career happens and survives, and although I kinda get it, still, it seems a little uninformed overall. Music like this don't exist in a vacuum, nor is being a girlfriend automatically the only explanation. There's, uh, life involved, ok?

Those Blakey "drum records"...many are similar, none are alike, though. None suck, but none have ever stuck me as "essential" in any way.
I myself prefer less "American" versions of that type thing, although I'll stipulate that their "American-ness" is probably what Blakey was aiming for. But give me Side 1 on Mongo's Up From The Roots any day.
