Three musicians were invited by the Red Ear Festival to tour six restaurants in the surrounding area of the festival (the so-called "Rotterdam Manhattan At The Maasdistrict") with unexpecting audiences.
These are recording of four of their performances, sometimes lasting two minutes before they were told (very politely) to go away. There's also lots of recordings of the musicians NOT playing.
Any unsuspected conclusions? Yes. Free Improv music goes down well with eaters of red meat (Gauchos!).
Musicians: Peter Van Bergen, Robbert van Hulzen and Lukas Simonis.
