Looking for 'sala' for playing music in bar/cava (Madrid)

Hi all,

Can you help me find me a place to play (like an underground cava) with my 3 man band for this Friday 17, starting at like 22 hours ? like in a cava or something like that? Informal setting. We need to be able to play with amps and we have our own equip.
I WOULD REALLY APPRECIATE IT!

The place where I was going to play cancelled on me…a bit last second...yes not ideal at all.

I already have 15 to 20 people that are confirmed to go/coming.
For the person that can help I would of course reward you with small token, a % of whatever cover we make. We can charge like 7 euro/person with drink included.

Thanks,

Bruno
