I assumed they were able to stay open bc she owned the space.I wondered the same thing. The website seems to indicate it is still open, but who knows about the long-term: https://villagevanguard.com/calendar-index/ . They list gigs through the summer. Let's hope there is someone crazy enough out there to want to keep the flame going.
Just imagine all the musicians she rubbed shoulders with over her long life. And all the live recordings at the Vanguard - she probably witnessed them all in person. Amazing.
