Look, I love a good jam band just as much as the next musician. But my girlfriend - who is very not musical - is only interested in seeing live acts at a bar that are playing music she can dance or sing to. If you're not playing a bunch of tunes she knows, she's not interested. I would wager that's the case for most bar patrons.
Go to a bar with a jukebox and see what music is played. Not many blues songs with lengthy solos, mostly popular music from any given decade. I also love playing deep cuts, and jamming out over some changes and soloing a bunch, but nobody else does.
Another bit of evidence - I go to a LOT of bars with live music. The bands that pack 'em in and everyone stays play the songs everybody knows. Most even have some backing tracks to play along with for more modern pop songs. They'll play some rap & hip-hop, even. This is all stuff that the crowd knows and loves, and they utilize the backing tracks for horns, extra key parts, synths for the rap/hip-hop stuff, etc. And when they play classic rock songs it's likely just a click track in their IEMs. On the other side of that, I've seen a few bands that play music that *I* definitely like better (deep cuts, blues/folk covers, etc.) but there's never a good crowd and the crowd is never that into it.
Just sayin', you're not there stroke your ego, you're there to play what the crowd wants. If the crowd isn't there, neither are you.
