The website would be your best bet for that answer. Two many too list. My favorite is Frank Solivan and Dirty Kitchen
I saw Dave Van Ronk and The Reverend Gary Davis in the early 60's.
If you hit their website, you will see the list of events, and know that most of the performers in the singer-songwriter and folk genre have performed there, everyone from Bob Dylan in 1960 to Peter Mulvey to Richard Shindell to Del Ray, Peter Mulvey to Don McLean to Al Stewart, and that doesn't count new acts like Darlingside.
Too many to list here. Recently I've seen great shows by Sawyer Fredricks, as well as my local fav Maryleigh Roohan. Check their website to see the history.
All I personally know about is The Bobs.
