During the early to mid 2000s, Mike Bullock ran a record label called Chloë. One of its releases was from Eric La Casa, Jean-Luc Guionnet, and Dan Warburton. It was entitled Métro Pré Saint Gervais and, as its title suggests, was recorded live at the Paris Métro station. The recording took place on a late July evening in 2001 and found the three musicians "experimenting real-time music in daily life.” Guionnet played alto sax, Warburton played violin, and La Casa used his microphones. Swarming, Eric La Casa’s label, has just reissued it.
