For jazz lovers, as well as for all those people who haven't discovered it yet but may do it soon, in the link below you can all see an interesting report covering some good recommendations for this month in Madrid. It also informs about the best jazz venues in the city. Good in case you didn't know where to go to enjoy nice moments with good live music.
Unfortunately it's only in Spanish (a bit too long for me to translate it, sorry), but it shouldn't be a problem for most of you. At least as regards identifying names and places.
Maybe we meet in any of the suggested concerts. Enjoy it :-)
