Jazz clubs--why does the music stop so early in BA

#1
I'm was pleasantly suprised to find that there are places in BA that have live jazz but I've been dissapointed that the music stops so early when other clubs go so late. So far I've been to Notorious and Thelonious Bar. Is there anything else that I'm missing? Also does anyone know where I would go to buy tickets for the Jazz festival at the end of this month?

Hi!
There is a very cool place called Pedraza. It is a house on Manuela Pedraza about two blocks west of Cabildo in Belgrano. There is no sign on the door but usually one sees people coming in or out. It goes pretty late and pretty good jazz musicians show up for jam sessions.....
Definitely recommend it!
