Hola tristis! You may have already looked at this thread in a search for live music on the board, but just in case you missed it, click
here for some suggestions. I had posted an article from the NY Times and there were several replies that included ideas and recommendations for places for music.
I was at Cardamomo briefly this past summer, and while there wasn't live music while I was at the venue, they did have great flamenco music playing! I really enjoyed it and would definitely go back to see a show there.
