Shh… don't tell anyone, but some friends of mine in Barcelona (including a certain bearded Belgian) have started putting on lovely secret shows in charming locations around the city. They're called Indies Keeping Secrets and they've already got two lovely & cozy little shows under their belt (one in a living room and one in a barber shop).
So if you live in Barcelona, you should really get acquainted with their Facebook and Twitter so you don't miss out on any future shows (they are, after all, a little bit secretive). And if you make music and are ever planning on being in Spain (you should, it's pretty damn lovely there), you should drop them a line about doing a show.
But you didn't hear any of this from me.
