Gregoire Maret - harmonica
Luques Curtis - bass
Ruy-Adrian Lopez-Nussa - drums
Harold Lopez-Nussa - piano
They were mid-way through this tune, to the point where Gregoire and Luques improvise together, when someone in the audience had a medical emergency. This is when that issue was resolved (the guy looked ok) and they started up again. The first half is gone, sorry.
