Here's my challenge:
I'm looking for a former place of business involving entertainment and libations (or specifically, live music and heavy drinking). When the place was originally opened, the generas of music that it planned to feature was bluegrass, country and blues (not necessarily in that order). While it never did quite succeed with its original plan, it nevertheless became one of the most influential* music scene locations of the latter half fourth of the 20th century for a different genera.
Where/what is/was this place?
By the way, it's closed down now. But Google Maps still has a reference to it.
*[Edit: If "one of the most influential" is too strong of phrase, then "one of the most notable" should safely suffice.]
