"La Maree Haute" stands for "High Tide" and it comes from the lovely and talented Lhasa de Sela, a Mexican-American who sings in French and has a brand new spanking 3rd album out.
It was featured on the off-montage from this weeks' RESCUE ME (episode "Wine"). I guess since the episode concerned a French journalist simultaneously trying to get into Denis Leary's character's pants and writing a book about 9/11, it was appropriate. Why do women throw themselves at this character?
