Viva Jazz!

Nothing is more depressing than an empty bar bar during open hours. Well, an empty one when there is a decent jazz band playing is probably worse.
I stumbled into the Dawson on thursday night and heard the Tal Shtuhl Trio performing. One advantage of an empty bar room, well, nearly empty, is that no one will sing with the band as two of six customers did that evening, One worried because she was wearing sweat pants. (Never knew there was a dress code for jazz.
The music made me wonder what places are left to enjoy a jazz ensemble. I admit I came to jazz pretty late (late teens/early 20s). A bartender at the steakhouse I was working at at the time loaned me a few albums. I still enjoy them today. Recently I was fortunate enough to witness Christian McBride, Lisa Henry and the 'Jazz Ambassadors' from the Thelonious Monk Institute perform for students at Shawmont Elementary. (Read that story here. Video is posted below.)
But with Philly's deep roots in Jazz music and culture, what is left, besides Chris' Jazz Cafe? With Ortlieb's gone, will and do bars like Dawson fill in the gap? In this era of electro-auto tuned, strip-pop and cover-bop, will anyone go to listen to good jazz anymore?
